Try adjusting LOCAL CONTRAST under ADVANCED PICTURE SETTINGS from HIGH to MEDIUM or LOW and see if that helps.
If this is the same problem I'm having, I don't think it's local contrast. It's a problem with this TV and Dolby Vision when the screen should be pure black.
In Mindhunter, the problem was in the first five or so episodes. It happened between scenes and even between individual end-of-episode credits, like when PRODUCED BY switches to DIRECTED BY (where the screen should be completely black in-between). Instead there was a weird light gray-ish screen for one to three full seconds. When the next scene or credit starts, the screen will show it normally. There's no real flickering. I haven't gone back to check to see if it is repeatable on those episodes. This happened on different nights with the TV powered off and on several times in between.
On Stranger Things 2, the issue is a completely pure white screen. During a transition between scenes, where one scene ends in black and the next scene begins in black, there will again be one to three seconds of pure bright white. Again, this happened maybe a dozen times total on multiple nights of viewing.
There's obviously some problem with the TV handling Dolby Vision information from Netflix. When it's told to show a pure black screen, it bugs out and displays the weird gray or pure white. It has never happened in the middle of a shot, only on edit points. I believe it's only when the editor has inserted frames of pure black into the footage between scenes, but that's just a guess.
My only access to DV footage is through Netflix/Vudu/etc. I've only noticed it during Netflix.
