I seriously doubt Nasa has got any of these wrong, but their goal seems to be for scientific exploration which to me suggests their main effort is contrast enhancement rather than human understandable colour reproduction (imagine if your camera was tuned to find differences in skin tone and blemishes rather than as a reproduction of what you remember a face as). It would be interesting to see what we can do with the data from before mutation.
