Their example replaced gray with pure white, and I'd guess that the former is far more prevalent in the world than the latter. They also complain about colors being too saturated (even though the colors they talk about range from 60 - 80% saturated, and are in no way "pure", ignoring that such a notion is an artificial one to begin with). But I'm not sure why prevalence in the real world is relevant at all. We're not talking about some Samsung claim of being inspired by nature, and skeudomorphs are not the goal. I don't think natural prevalence is relevant at all. So white is "better" than gray. Less saturated is "better" than more saturated. At least in the author's opinion. Narrative beyond that (such as the notion that some colors are too easy) is just trying to build some structural justification for those notions.
