I did. The gentleman at Micro Center was nice enough to let me plug in my 13” M4 MBA with Stillcolor and Better Display enabled.
The improvement was incredibly minor. I did my best to run a 240 fps test for grey color flicker (I changed the background to grey). I couldn’t say for sure but I did pick up flicker. Full disclosure, it could’ve been from the LED lights in the store.
My sense from testing the MBA with other non-Apple monitors: if you find an internal MacBook screen uncomfortable, you will likely find the Studio Display uncomfortable. The MBA is clearly dithering on the hardware level and it would be unlikely that the Studio Display isn’t doing the same, or taking the dithered signal from the MBA.
I asked the Apple Store if I could plug the MBA into the Pro Display XDR. They wouldn’t let me. I don’t have $6K to try it at home unfortunately. Maybe I’ll win the lottery! 😂
