Dolby vision on Apple TV 4K blacking out

Ive had my AppleTV 4K since it’s release. Have set to 4K hdr, with match content. Ive watched countless Dolby vision programs without issue. When I installed the appleTV I also installed a certified high speed hdmi cable. Tonight (June 17, 2021) I went to watch a Dolby vision program and It goes to switch into Dolby vision and it keeps kicking in and out, black screen, then back. What changed? Watching the same content direct from the tv plays Dolby vision without issue. Did Apple TV update today?

I should have made clear that I'm seeing the problem on the latest AppleTV 4K (2021), even with tvOS 15, although it may be somewhat better. The firmware in my C1 was just updated, and may have helped a bit but hasn't totally fixed the problem.

I did find that switching the AppleTV to 4K HDR from 4K Dolby Vision helped a bit.

Thanks for indicating that the problem isn't specific to LG devices!
