Same issue, but an interesting wrinkle with mine. LG C9, same update as everyone and Dolby Vision is broken between my Apple TV 4K and Denon AVR.
what is interesting is Dolby Vision runs just fine between my Sony UHD player running through the same Denon to the same TV.
So it has to be something specific to the LG and the Apple TV 4K (I have the 2021 Apple TV 4K by the way).
Well shit.. like i said. Nvidia shield here.. so not specific. Works fine directly connected to my 77c9. But not working like it should while going through my Denon receiver.
C9 Update - 05.10.04 - Can no longer connect to Dolby
