As long I can remember, someone from the dev team told me that Plex relies on FFmpeg for that part and uses Exoplayer for the player capabilities, But I’m not 100%, if that is the case, then we need to wait for FFmpeg support.
Hope it arrives soon!
The race is now on, Emby have a beta version to test DV MKV support

Emby or Jellyfish actually appear to care and actively respond and try to rapidly improve.

I’m just quoting this post from a Plex employee from back in May for people wondering about the ExoPlayer update.

Im pretty sure that Plex wants to support it across all apps instead of just Android (Exoplayer) 
My vote also for this feature!
I want this too!
+1 for this! Any chance of a Alpha\Beta?
Honestly, this is by far the number 1 feature I’m waiting for. Obviously, we all want this to work without hiccups when it’s finally released, but I’d love to get an idea when we might see it now that we have a final spec, software to create and test these files, and competing platforms already starting to add this feature.
I have over 50 DV UHD files, with more to be ripped, that I’m waiting to watch and test so hopefully this won’t be too much longer.
I would have to ask if anyone could actually see the difference between HLG/PQ and Dolby Vision.
Is it the name?
HLG/PQ HDR works just fine at the moment, I don’t see it as a high level must have. I feel that there are a couple of other things that need tidying up first.

Every review I’ve seen says “I guess DV is better than HDR10, a little, in some places.” It seems like it’s as much about who did the color management and mastering as anything.
Have you encountered HLG media? What’s the source? I’m aware of a couple test files, but that’s about it.
There’s lots of HDR10, but I thought HLG was only being used in live broadcast, and not many TVs support it yet. I’ve been kinda following the HDHomeRun ATSC 3.0 tuner campaign, but that’s been delayed.
I work in Broadcast so I have seen a bit of HLG. I should have added HDR10 in the ‘can you tell the difference’ statement.?

Personally, Dolby Vision on my oled setup makes a big enough difference to change the viewing experience.
To be more specific, dynamic metadata makes the difference.
I assume that HDR10+ will give a similar advantage, but I can’t test it.
To see the difference, you have to look for the right content.
You need content that has large variations in overall brightness from scene to scene.
The difference can be seen in the extremes, as in low light scenes or really bright outside scenes.
The farther away from the contents average brightness, the better the difference can be seen.
HDR10 only gives a best fits all tuning of the image, where only most of the scenes look their best.
Dolby Vision allows to individually tune each scene, where every scene look their best.
For example, the sinking ship scene in Tomb Raider (2018). The waves are significantly clearer in Dolby Vision, making a bigger impact of the threat of the situation.
Another example, the scene in Venom (2018) where venom has a face to face with Eddie in the middle of the water. In HDR10, you pretty much only see the dominating yellow lights reflecting on Venom. In Dolby Vision, you get to see the city lights on top of it, giving additional red and blue highlights, giving it a more reflective look.

I have a 77" LG C9 OLED and I have calibrated all modes (including DV) for white balance/gamma and CMS (no CMS calibration for DV, though). This includes custom tone mapping for HDR10 modes.
I rip my UHDs uncompressed into MKV as I value the lossless audio tracks over DV. When watching a REAL HDR (not a crappy HDR in an SDR container version) movie on disk in DV vs watching the same movie in HDR10, I find it hard to tell the difference. There are slight variations in color saturation between them but both handle peak whites and shadows very similarly. Hell, there aren’t any consumer TVs that can come close to the Rec. 2020 colorspace anyway.
At the end of the day we are splitting hairs unless you have a high quality, calibrated monitor/TV that can really highlight the differences, as little as they are. That said, DV is nice and something I would prefer for my rips over HDR10.

What do you mean? x265 10-bit-encoding for 8-bit-color files? If so, those aren’t “fibbing”; the 10-bit-encoding process is more space-efficient even for 8-bit, SDR color space streams.
If you’re referring to something else I’m curious what.
There’s a LOT of opportunity for improvement here. We’ve gone from 6 to 8 to 10 bit panels in 10 years. Illumination is still the weakest link.
Especially for straight MKV rips!
I am talking about “Fake HDR” where a UHD BD movie advertises “HDR/DV” but they don’t really go above SDR nits. Here is an example: https://www.youtube.com/watch?v=C2vsxdaRA7w

Ahhhhhh, gotcha. Thanks for the link. Vincent is always awesome.
That Canon reference monitor? It’s $1000 per inch.
That reminds me of the “Fake 4K” issue.
Yes. Fake 4k and Fake HDR are awful marketing problems for UHD right now.
That said, I understand that some cinematographers do not necessarily like the Rec 2020 color space or that level of luminosity in their films. HDR is not the only consideration. But, marketing for these movie studios can’t sell something as HDR if it isn’t HDR. Most Marvel movies were mastered and/or recorded at “2k” because of the special effects. They are effectively upscaled for UHD (hence “Fake 4K”).
Also, we need to remember that what we see depends on the creator’s intended vision. I have seen smart reviewers complain about film grain in a 4K movie in certain scenarios where the director’s intent was heavy film grain. You can’t dismiss that when looking at PQ.
I also rip UHD’s into MKV containers and do not re-compress the file. MakeMKV is now able, as of 1.15.3, to construct dual layer DV, but PLEX cannot recognize it, yet. Now that it’s possible to rip both Dual-Layer DV with object-based audio in an MKV container, how long until PLEX can support it?
As far as why this is desired for me personally, I prefer the added color saturation and nit brightness over HDR10 on my P-Series Quantum X. I already have a lifetime PLEX Pass, but would be willing to shell out a little extra $ to acquire a license to play back DV, if and only if, it comes to that. Adding features like the ability to play back DL-DV gives consumers reasons to continue acquisition of discs, which adds to PLEX product security. If the end ever comes for physical discs (UHD), then PLEX would need to shift focus, anyway.
Could I just clear something up. 4K movies on disc are compressed already. The data rate of a an uncompressed 4K movie is around 3-4Gb/s depending on bit depth etc. 4K movies on disc are anywhere between 80Mb/s and 140Mb/s.
When people say that they rip the UHD ‘uncompressed’ what they should say is that they don’t re-compress the file on disc and loose more information from the picture.
