i’m posting results of tests I have done trying to playback BT2020 (HDR) MKV files (2160p) on my LG OLED TV.
LG player over DLNA: OK - HDR Triggered
LG XPlay (unoffical Plex client): OK - HDR Triggered
Kodi on Shield: OK - HDR Triggered
Plex on LG: NOT Working - if it starts playback is with vertical lines all over the screen - HDR NOT triggered
Plex on Shield: PARTIAL - Playback OK - HDR NOT Triggered (hence wrong colours)
Plex plugin for Kodi: Not working
As you can see Plex can not playback properly under any combination I tried. Unfortunately XPlay (a third party Plex client) works better than the official one.
If you guys are interested in fixing this I can provide you download link with samples.
Hey, I am experincing a simular issue with Chromecast Ultra, which does support 4k and HDR; sadly Plex had not updated its streaming profiles located in /usr/lib/plexmediaserver/Resources/Profiles/
for Ultra, I du suspect same issue is for LG, since i can not see any LG WebOS specific I’m leaning towards Universal TV.xml, you can try editing it manuelly

Mine triggered HDR w/ 4k@60Hz and setting Refresh Rate Switching to ‘off.’ With Refresh Rate Switching set to ‘on’ HDR was not triggered.
Same with Kodi, it would only trigger HDR with 4k@60Hz and no refresh rate switching. I also answered my question and it would play over DLNA from the LG Photo & Video app.
Too bad the quality of the test file I downloaded is rubbish.
I basically have the same results, plus what @timstephens24 said. It actually triggers HDR when you disable frame rate switching on the Shield Plex client. Which is weird.
However, I am also experiencing crushed blacks when the Shield is set to 4K @ 60hz as well as a prominent oange/yellow-ish tint in the picture (when comparing to the same picture viewed in the webOS Plex client).
I do not have a Sony TV, so I am unable to test. but looking at the different Sony Profiles that is the one that makes the most sense.
Sadly by the looks of the profiles they are all set to 1080p, with 4k becoming ever more abundant, plex needs to update profile to support accommodate this , that also goes for Chromecast Ultra, which has nativ support for HDR and HEVC, which nither is reflected in profiles.
