I was playing Captain America: The First Avenger from the Disney+ app on my 55" QN93A television. The opening scene show really noticeable blooming artifacts around highlights and the borders of the frame.
I would much rather watch this in a low range 2015 LED TV as it wouldn't show this kind of problems on this scene.
Samsung SHOULD correct this, update the algorithm to turn off local dimming in scenes like that one. This is not the quality I spect from a high-end Samsung product. I'm very disappointed.
