The consensus here seems to always be leave in SDR and use match content, but I’ve had no issues with leaving Dolby Vision on all the time. SDR content like youtube and TV shows that were never mastered in HDR look 100% fine to me. Part of the Dolby Vision spec is that it forces your TV into it’s most color accurate settings so why wouldn’t I want that as well? Using an LG C2 by the way.
I noticed this problem with Ted Lasso, too. I’ve seen it happen when two characters are talking where one is in front of a bright background and the other is in front of a dark background.
I also noticed this problem with Frasier 2023 on Paramount+, but I couldn’t determine any reason. It is streamed in 4K DV.
