The Article by Alyssa Miller goes into the issue which is similiar to the one on the big battle at the end of game of thrones. And honestly we didn’t see it too much, but I have my TV properly calibrated or at least as well as it can be, and we have overhead canned lighting and can do it dimmer over us, so likely the room is darker than for the last season of Game of Thrones, but we do see this more and more. They are color correcting way too dark for TV.
And I think the problem is obvious. Color bays are too dark and they use too good screens in the dark. That is absolutely fine for films which are meant to be seen in a darkened room, but homes have light, and most people don’t watch television in the dark.
Honestly there should be a higher level of ambient light in editing bays for TV, to take account people have lights on in their house. And have a consumer display to finish to as well, to check how it looks.
I know on these signature shows they want you to turn off the lights and only pay attention to it, but that isn’t an option for everyone.
And if there are significant complaints, you are doing the grade wrong. You need to remember this is going to be viewed by people at home, not in a darkened theater!
