I have dual studio displays and I have noticed (when the screens are off) that the glass is coated with a different colour. One is green tinted and the other is purple tinted. I have looked at my old iMac and that had a purple tint to it also.

I have also found that when wiping the screens with a microfibre cloth the green tinted one grips the microfibre more, but it glides across the purple tinted one more easily.

I wouldn't even have noticed if it wasn't for the fact that I have 2 displays side by side.

Quality wise it makes no difference to the image and I can't even see it when the screens are on. Just an observation really.

Same - purple for me. I have been noticing it side-by-side with my iMac 2020 27” screen that doesn’t have it. Unlike you, I see it even when the screen is on. It has been a bit distracting compared to the apparently non-coated iMac screen right next to it.

Hey guys, I have bought three and noticed the exact same thing. One is green and two are purple. It actually does affect the picture as the wavelengths of light that reflect are slightly different. I am contemplating contacting AppleCare and requesting a replacement of the odd one out.
