CMYK images have a color shift

I dumped a bunch of jpegs into a research folder so that I could write captions for them for a project. The colors were completely off on a select number of them and when I examined the files in Photoshop I realized that the ones in CMYK were the problem files.

The files show with their normal colors in the Finder and in Preview–why is there a problem in Scrivener? (using the latest beta version 1.08 but the problem is the same in the latest, non-beta version).

Presumably something to do with the way Scrivener draws images to the screen, though it uses in-built Apple methods for doing this. Could you send me a sample image with this problem to so I can test?
