MacBook Pro Display too yellow compared to Studio Display

No matter what I do, the colours don't match at all between my Apple Studio Display and my MacBook Pro.

And you will, literally, never get there trying to do this by eye.

I tried the Reference Modes. Not only are they too dark, they don't look AT ALL the same on the Studio Display and the MacBook Pro.

I also tried the "Fine-Tune Calibration" mode; I was expecting being able to calibrate my monitors like before with the little sliders and everything (Display Calibrator Assistant), but all I'm getting are input boxes...

The built-in Calibration function, as I've already stated, is a complete waste of time. It can only guess what your monitor looks like. When you start the function, it clears the LUT and displays what it can only assume is a perfect 6500K, 2.2 gamma display with a predetermined luminance value.

That might be a fairly accurate guess if the monitor is less than a month or two old. After that, forget it.

Again, no matter what I do, both displays look very different. I'm not expecting them to be 100% identical, but I'm expecting my brand new 7000$ set-up to be a little more plug and play than that.

My EIZO CG279X monitor alone cost $2,300, and I still know it needs to be calibrated and profiled on a regular, scheduled basis.

All monitors drift. There are no exceptions. Doesn't matter how much you paid for it. In an almost 100% manner, LCD and LED monitors tend to drift pink as they age. When you eyeball it back to what looks neutral to you, the OS sees you're adding green. It has no idea why, even though you know it's to counteract the pink cast. The OS only knows you seem to like a greenish gray balance, and that's what you printed grays will look like.

I've been spending countless hours trying to figure things out with no success. As I said, I see the differences mainly when I'm on Safari, TextEdit, or when I'm on the Finder with windows open; the big white windows show the warmth and brightness differences the most. However, when I open my photos in Photoshop, they seem almost identical on both screens. 🤷‍♂️

And that's just one problem with a non-color managed monitor. Some apps don't work well with ColorSync. Others, not at all. On any monitor that has not been properly calibrated and profiled, there's no telling what each app will display.

I'm at a loss. I can't spend more money buying a monitor calibrator. I just want both displays to be closer in appearance than THAT:

Sooooo, you've spent 7 grand on your Mac setups, but you won't spend less than $300 to properly color manage the displays? If you ever expect them to match, you need a monitor profiling system. If you ever expect to get professional color results, there's no way around it.

The Calibrate function can only guess at what you're doing. It has no clue - at all - what the monitor's gamut, color range, gray balance, or anything else actually looks like. In other words, it's pointless to even use it.

A monitor profiling system knows exactly what the panel response is. That's what the hardware is for.
