I just picked up a new SG 13" M1 MBP. I can confirm this issue persists. This keyboard is literally pink/purple when compared to the white of the screen and most noticeably of the Touch Bar. At this point these keyboards have been out for a year, so I have to imagine this isn't some manufacturing defect and is instead actually considered normal behavior.
Have a 16" MBP which is pure white. So I can put them side by side and easily see the difference.
