Edit: see very bottom of this post.
Under firmware 7.7 I had went to the secret HDR setting screen and changed the setting from 4:2:2 to 4:2:0 to fix an issue with audio dropping out.

I just updated to firmware 8.0 on my Premiere+ and figured I’d switch back to 4:2:2 to see if it was working, but the secret screen no longer shows whether 4:2:2 or 4:2:0 is in use, nor does it allow changing anything. All it does now is show what’s supported which says YCC420 and YCC444 are supported. Was 422 support removed?
How can I change this value back now?
Never mind I found that this was moved into the System -> Advanced System Settings -> Advanced display settings -> HDR subsampling settings.
