Is this likely an example of the HDR encoding on the disc? It looked really ugly. I tried taking photos, but my phone just isn't picking it up.
See, this is my issue with Blu-Ray forum their reviews at the moment. I have no idea how this scores a 4.5/5
While the colors and black levels overall look pretty good, the artifacts and compression issues are most certainly enough to drop this down to a 3/5 at best.
I may not understand the terminology for a lot of these technologies, but my eyes can tell a good transfer from a bad one. Like, I seriously can't believe they gave this film the same score as Chappie, The Martian, the original Ghostbusters, etc. when those films had none of these issues.
EDIT: so, as it turns out, this is an issue with OLED handling "near black" scenes, and doesn't appear to be a source issue.
This is incredibly disappointing. If I had known these issues were so pronounced with OLEDs, I might've considered going with one of the newer Sony LEDs as they still support Dolby Vision.
I'd like to chime in on this, as well. I noticed what you were talking about here and I thought something wasn't right. I then I checked my HDR settings and found that my brightness setting was set a couple clicks higher than normal. Not sure how that happened, maybe I was fiddling with the settings and forgot to set it back.
After I set my HDR's brightness back to the normal setting I checked the scene again and the banding disappeared. And I continued watching the movie without any problems.
I also double checked the standard blu-ray to see how it compared in various scenes, including that scene, and sure enough my previous setting showed the brightness was different, but after bumping it back down to normal, the scenes looked very similar.
So, I'm thinking that this maybe a problem still with how the disc was encoded/compressed, but only really noticeable when the sets are not calibrated properly. Because, as you said, despite the LG's having less than ideal near-black handling, this was not noticed on other discs at all.
