^This. For some reason during that title card screen, 2 more visible black bands appear towards the right hand side of the screen. If I lower the black level setting to 48 the overall black level lowers enough so that they blend in.Send a different pic, a 5% greyscale, (link at end) That is about how that shot looks on my oled. The banding seems to be from the way the director and colorist shot it. Since it’s at 5pct Grey the banding of the oled is very visible in that opening scene. It’s a horror shot for most oleds it seems.
Try a 5% grey pic and post it ... I use this from YouTube. The 5% hey is the on to post a pic on ... when it says greyscale the first shot is black at 24 sec in to about 29 sec is the 5%. Pause and look and send a pic.
