Laptop OLEDs aren't usually the best wrt color accuracy and uniformity. I've tried two. One had green splotches across the screen, the other just displays a certain range of gray shades with a green tint (so e.g. a black-to-white gradient test image has a green band in the middle). And there's always a static noise pattern of sorts due to non-uniform pixel brightness.
