Could be how it was graded. If the colorist did not use a scope on a display that does not go to 0, then black will be elevated. e.g. The montage was graded on a Pulsar with 0.005 black. That is what is in the metadata per Dolby's request. The colorist, at Dolby, used a scope to put black at black.Hey Stacey, I'm sure this is true but I've been seeing some weird things with my C9 from HDR blu-rays. I've noticed that in-frame elements that are true black in the SDR and Dolby Vision versions of a movie are not black in the HDR10 version with Brightness = 50. Letterbox bars are black, and black level clipping test patterns on YouTube look correct, but the content itself looks bad. Fade-in transitions from "black" are marred by posterization, for example. Lowering brightness to 49 tends to fix most issues, but I'm sure it's clipping shadow detail. Do you know why this is?
How is the black background on the HDR montage on our disc? Any scene with the raptors or honey have primary black at 0. (64)
