Setting Brightness to 49 gets everything in line. Using Cinema User preset with the Oled Light and Contrast cranked to 100. Some have reported and measured the blacks in the C7 master thread to perform similarly. However other titles like Luke Cage, Daredevil etc, dont seem to have these elevated blacks using similar settings. Eg. Brightness at 50. So I'm not really sure where the problem lies.
Exactly. It isn't a panel or firmware issue in any way, because different titles are behaving differently. It's got to be an encoding issue. When I can sit there and skim through the entirety of A Few Good Men in a totally black room and never once see the letterbox bars at 51 brightness, and then see them on Rambo II at the same brightness setting, then something is up with the software, not the player or panel. This is not JUST a DV issue or I wouldn't be seeing different black levels on the two discs in question, which are both HDR10.
The base black level on both of those discs are clearly different. Like I said, I don't have a ton of UHD material right now. About 10 discs. So I think I'm just going to put little stickers on my 4K discs with the proper brightness setting for that particular disc. It's irritating, but apparently necessary.
Again, if anyone else wants to test and confirm:
LG OLED E6
A Few Good Men (gray bars begin at 52*)
Rambo: First Blood Part II (gray bars begin at 50*)
*decrease both by 1 if you have not changed your sub-brightness to 127.
This MUST be tested in a completely black room.
