Kendallsj The difference in color tinting showing up specifically in these screenshots is just because of Wallpaper Tinting, which slightly changes the background color of windows to match the wallpaper. This can be turned off in the same appearance preferences window shown in the screenshots, which should make both screenshots appear the same.
A camera photo with both screens displaying a solid background or picture would be a better way for us to compare the screens themselves.
However the discomfort is definitely coming from an actual screen difference (different manufacturers?) between models, which I've also personally encountered.
I hate my 2021 14" Pro M1 Max screen, it's actually the worst screen I've ever used in my life — literally the laptop that made me realize I even had problems with screens in the first place. One friend has a 2023 14" Pro M3 Pro, which has the same exact problems as mine.
However, another friend has a 2022 16" Pro M2 Pro, and for some reason, I'm totally fine with that screen. It feels like a completely different panel, way sharper, more realistic colors, no weird glow around text, less "vignette" effect at the edges, and SO much more comfortable to look at. All 3 laptops are marketed as having the "same" Liquid Retina XDR display and are running the latest version of Sonoma.
Very confusing experience but definitely confirms that there are very significant panel differences between each mini-LED MacBook Pro.
Also, weirdly enough, my terrible 14" M1 MBP actually got slightly better with Sonoma, I feel like it noticeably improved the consistency of frame timing in 60FPS mode. I don't think Sonoma is the issue, because my 14" MBP sucked even back when it was on Monterey.
