I'm not sure the black jacket analogy applies, since coral coloration is so variable due to lighting and other conditions, but I do get your point.
My point was simply that the lighting between your photos and the LA photo do not look very similar at all, so it's very difficult to form any useful opinion about the coral's color. And I still don't believe it's in LA's interest to doctor their photographs, so I find it hard to believe that they would spend the time to do this. If that is indeed the case, then it's safe to deduce that the same coral can have the appearance shown in both sets of photos depending on the lighting or other factors that we don't know about.
