I tried the iPad Pro with Nano Texture and found the display to have a rainbow grain, especially on pure white backgrounds.

Are you bothered by anything similar on the MacBook?

You’re not the only one to mention that in this thread. I’ve had a nanotextured MacBook as a daily driver for about six months, and I have no clue what you are talking about. Maybe the issue is iPad only?

Rainbow isn't really the right term. It's more of a sparkling effect. Apple actually uses the term "sparkle" for this characteristic in their patent for the display treatment (see para 0073). They also mention that different diffractive layers can be used to minimize the effect, so it is possible that the issue is worse on some devices than others.

I personally haven't noticed that. I am also primarily coding & writing rather than image editing or such so am less sensitive to things like that fwiw.
