HDR10 Weird colors on Android TV - Kossuranta - 2025-10-10

Hi!

I'm running Jellyfin server in Docker on Unraid server with Intel N100 based system.
Most of the movies and TV shows have been working just fine, but now encountered issues with a movie that's 4K HVEC 10bit HDR10. Everything works just fine on my PC with Jellyfin player, but on Android TV colors are all weird (mostly green and purple). I believe that the HDR10 is the issue and tone mapping might solve it, but it's using "Direct playback" so it's not encoding => no tone mapping. For testing I managed to force encoding by limiting bitrate, which made colors better, but still off (over saturated I guess).

My TV does support HDR10, HLG and Dolby Visio, so any ideas how to fix this issue?
And as a bonus question, how to change language for the TV client. I have Jellyfin in english for browser and PC client, but can't figure out how to set language for TV as it's now in finnish.
