I myself saw "Road House" on Thursday, 4K stream. A lot of dark scenes, perfect for OLED. But also very vulnerable to bitrate related quality problems. And it was fine.

But other examples, like the first season of "Reacher", look like shit in 4K. Many artifacts resulting in skintones that get pushed into green or red. Super weird.

Good encoding comes a long way, and not all services go the extra mile.

Dark scenes don't have higher bitrate requirements than brighter scenes. The problem with dark scenes in movies is simply that video encoders have been tuned based on shit perceptual models that don't match how humans see things. If anything, something encoded for a constant bitrate will have less problems with dark scenes than something targeting an overall file size but with the encoder given leeway to assign bits to different parts of the movie.
