I've on occasion seen the other thing, watching DV content from my ATV: After a scene transition from a dark scene to a bright scene, it can take a second for the screen to brighten up properly. It only happens on some Netflix content (Ozark IIRC) so I have assumed it was an encoding thing in the content itself.
Yeah I noticed this as well once in a while. This is pretty similar sounding to the HDR luminance issue
everyone was making a big deal about with the 2018 models. I've only experience this issue on Netflix as well, and I don't know if it is genuinely just a rush -job from Netflix on a TV show, vs a Hollywood movie, or just that I've seen more DV content on Netflix than anywhere else.
This season of Series of Unfortunate Events
displayed that as well as a lot of ASBL issues. The last episode was almost 100% bright so there were no ASBL issues, but the issue you described was present. Theres a scene that keeps cutting between 3 closeups and the differing luminance levels took a second to catch up.
Netflix does seem to want their shows to be far darker than the average HDR10/DV film, which may point to them being part of the problem via mastering. Even notoriously dark films in SDR like Harry Potter 6,
or films that take place mostly in dimly lit environments like Unsane
have much brighter average levels than Sabrina
and Hill House
did. Either way, Netflix or LG really should look into this. I think since the issue effects something as fundamental as brightness it's easily noticeable by the general public, not just pixel peepers.
