I just remembered I have a direct experience, since one of my photographs appeared on a cover of a photographic magazine. While processing the image, I was careful to retain "believability," i.e., avoid over-saturation. I was surprised to see it rather saturated on the cover. Not terribly, but still more than what I sent them.
And you know what? I like it that way. There, on the cover. It just works better there. It suits the cover's purpose, to attract otherwise fleeting attention of passersby. There, on the cover, it also competes with all the big, bold, screaming headlines, and thus benefits from the extra kick of saturation.
Would I print it that saturated as a wall decor or gallery display? Probably not. Because of a different context, different viewing environment, different viewer's expectation, different life span.
