On a side note, for me atleast, changing the following settings work very well for SDR use and now almost match my NEC EA274Wmi including whitepoint :
Mode: TrueBlack400 (all other settings are default)
Windows HD color : On, SDR/HDR Brightness ratio: 19
NV panel Red Channel brightness boosted to 52 % from default 50 eliminates the native greenish white point.

Hey man, wanted to thank you for this adjustment. Saved the monitor for me. Now I'm finally happy with it - I was hating the original green-ish tint, and was about to return it.
