Unfortunately its way warmer than my 15 pro max as well
As I mentioned before, my 11" M1 as well as my several previous iPad Pro models, have all had displays that near-perfectly match my calibrated MBP. If I hold my M1 up next to my MBP with the same image, the two are nearly indistinguishable. And while I don't intend to edit on my 15 Pro Max (which I believe is OLED, right?), I have compared the color between it and the iPad/MBP, and it's noticeably warmer/yellower, to the point where I would not feel it's too inaccurate to use even if I wanted to.
If the new iPads are even warmer than that, that's quite disturbing. My M1 is fine, so I have no urgent need to upgrade now (was merely toying with the idea), but at some point I'm going to have to. Maybe by then Apple will have implemented some kind of color management capabilities / white balance adjustment.
