Color Shift with M1 Macbook Pro (but not with an external monitor...?)
Finding a bit of a strange issue here on my new M1 MacBook Pro.
I've noticed that I'm getting a color shift between what I see in Premiere Pro and what I see in Quicktime or the internet. However this ONLY happens on the Macbook monitor itself and does not happen on an external, calibrated monitor.
Here's a few images demonstrating what I mean:
First - Screenshots from the Macbook monitor:

Premiere Pro on the left, Youtube on the right. Notice Premiere is much more saturated.
However if I take these EXACT SAME WINDOWS and move them over to an external monitor - the color shift is gone.

Again, Premiere Pro on the left, YouTube on the right.
So what exactly is happening on the Macbook monitor that is causing this shift in saturation? It seems that maybe Premiere is doing something "under the hood" depending on which monitor is being used. You'll also notice YouTube specifically (on the right) seems to match on both monitors. It's only Premiere Pro on the Macbook that is experiencing a change in color.
Now I'm fully aware of color management, and how different softwares display colors differently, and viewing environment and all that other jazz. That's all find and good - but it doesn't explain why the two exact same windows would appear the exact same (colorwise) on one monitor, but not the exact same on a different monitor. Nothing is changing except the monitor. It would make sense to me if the colors changed - but still matched - yet they don't.
Is this a Premiere issue? A Macbook issue? or something else?
The obvious solution is to always color on the external monitor, but this isn't practical for my workflow.
Thanks for your time. Happy to provide more information if requested.
