For DV Profile 5, Plex passes the file 100% as-is directly to the Apple player/decoder.
I’ll bet your file isn’t perfectly compatible with the Apple player/decoder. Most DV P5 samples from the Internet aren’t.
Can you share a link to the source of the file, OR the output of mediainfo -f, or if you’re using the latest version of PMS, the full XML Info for the file?

I have similar files that work well. I’m surprised (and happy) to see dvh1, that’s relatively uncommon, but is correct and necessary for Apple devices to play DV P5 content.
I get the same error if I connect an Apple TV 4K to a non-4K or non-Dolby Vision display. (Or using an Apple TV 3rd Gen, which doesn’t support Dolby Vision.)
What model Apple TV are you using?
Is it connected to a 4K, Dolby Vision-capable display?
In the Apple TV Settings → Video and Audio, have you tested the 4K and Dolby Vision Formats, so the Apple TV knows they’re available?
Are the Match Content options enabled?
Apple TV 4K, newest model, connected to a 4K Sony 850D - not a DV display. DV files do play through the Apple TV with other apps, though, just not Plex. ATV format = 4K HDR 60. Match content (dynamic range & frame rate) = Both Off.
