Played with calibration a little. The display tracks things so well in SDR there's no need for any correction in Windows, it is all under 2 dE. Only thing I did was adjust the white point a bit. I saw some people comment that MiniLED variable backlight is a problem because it changes white balance and color. So I tried it on Level 3 and the answer is that it does but not in a meaningful way. At very low levels the grayscale tracking isn't quite as good, just under 4 dE, with more blue than it should have, but it quickly gets back in check and goes down to where it was before. Gamma tracking is a little off, undertracks a little on the low end, but again only a minor amount.
It tracks the sRGB gamma curve, rather than 2.2. They are very similar, but sRGB is the one it is actually tracking, and it is very close to it.
While I wouldn't use variable backlight on the desktop because the zones are noticeable on the mouse cursor, it also isn't going to cause any noticeable color issues in game. The extent it changes from non-variable is very, very, minor. The display seems to be very color accurate, but more importantly, consistent. This is in Racing mode, custom color temp to get as close as I can to D65.
