Mine is 5 years old and pretty much uniform when showing white. I’ve been rotating the position and size of system icons ever since I got it in early 2023. However, after the previous owner, there is a vaguely shaped, soft-edged area in the bottom where dark colors (or any colors at low brightness) are noticeably darker than elsewhere. The blue channel is affected most so a hue shift occurs as well. It somewhat ruins the HDR experience of an OLED.
