Apologies if this duplicates other posts here. I’ve tried searching around on this subject in the forums and the issues around bit depth and autoswitching, but they all seem to discuss Chroma 4:4:4 content.
I’m on 8.95.6 on S905 (odroid c2) and when I try to play content encoded at 4:2:0 10bit at 4k with BT2020, it looks really desaturated and washed out. Is this because there is a problem 4:2:0 Chroma in the autoswitching?
I’m using a 2 year old Samsung Series 7 4k TV if that is relevant to my problem?
I suspect this is a known bug, but I’m having a hard time verifying that?
Here’s the details on some content where I see this problem:
