I suspect that Nintendo screwed up the calibration of the Switch 2 screens as well, to give the impression of a better screen than it actually is (and thus try to bring it more in line with Switch 1 OLED in terms of the "feeling").
The screen on my Switch 1, when compared to my monitor calibrated with external equipment, doesn't look too bad in terms of color accuracy (I'll test other images to be sure). I think the Switch 2 deviates much more, though.
