It looks to me like it's gone though slight color enhancement, and possibly a little bit of sharpening. Or, the photographer just has one boss of a camera. A lot of cosplays are enhanced slightly just to help bring out the color, since most of them are going for cartoon characters.
Indeed, that's why I asked. More to make sure what I was judging on is the construction/actual look of the armor and not the filter of Photoshop. I'd much rather see an unfiltered photo of a cosplay however if it is filtered and made known to be such, I don't necessarily count that as a negative either.
