Pro Display XDR colour not as good as on the Studio Display

Hi there,

I have both these monitors, but there's a noticeably better colour on my Studio display when I using Logic Pro. The XDR is almost slightly cold, and the greys not as deep (True Tone is on, fwiw). Logic looks wrong, by comparison to how it's displayed on my laptop, or the Studio display. Am I missing something? I thought this monitor had the best (factory calibrated) colour ever?
