To update. In terms of best picture in Coco’s intro with this test OMSC build, it’s definitely Apple TV 4K the best. Nice contrast, looks great. Then the Vero. I may need to check again because it’s very close and my eyes are burning from checking. And then the LG OLED - super washed out. Looks dreadful by comparison.

Checked again. No question Apple TV 4K outputs the nicest image. Vero is a relatively close second (my eyes need a break from this), and the LG OLED a VERY VERY distant third.
