I agree that any "special effects" like fake SSS and such would distract from the color map. But on the other hand I think that using gamma correction would actually be a good thing in this case, because the "yellow bloom" is quite distracting, too.

Also, since this is not a promo image as such, I don't think you need to be that concerned about misleading people.
