Assuming you are not delusional, this means the files were never corrupted (by writing bad data) on disk, but due to some problem that occurred on reading and/or presenting. The images you posted *look* like hardware induced to me (there is a tell-tale look to hardware-related corruption, or apparent corruption), because that's what I'm familiar with (not familiar with how that look could come from display/monitor profile). My present guess: ram is the most likely culprit. Why? because if image is displayed good after appearing bad, then it's probably OK on disk. Consider running memtest86 to check RAM (unless you know that the built-in Mac test covered all bases coverable by memtest86), and realize: it won't catch 100% of ram problems, e.g. DdeGannes (a fellow forumer here) had an image corruption problem like yours that was solved by replacing a ram card that had previously passed the ram check (don't remember which check he did) - such was discovered by a professional technician somehow. Please do report back if the problem goes away for good, or comes back - thanks.
