It would be helpful to have a status of the various driver statuses on the clients. I'm thinking something like:
Prod version:
Video Driver: Experimental brings HDR playback
Test Version:
Video Driver: Experimental fixes AppleTV's stupid lack of HLG (one can dream...)
This could go in the forum, FAQ, etc, but it really should be in one place, seeing as most client issues troubleshooting start with "what driver are you using?"
Also - it would probably be useful is there was some level of recommendation given - i.e. "If you have a 4K TV and a receiver with HDMI 2.x, use experimental decoders for Video and Audio" - thinking best possible experience with multiple setups.
