The hypothetical scenario of knowing all of the physical facts about what it is like to see the color red does not seem particularly possible to me even without the constraint that it happen without having seen colors before. Since we are assuming that Mary understands the color red to a dramatically deeper degree than any human actually has, I don’t see how you can conclusively state that her reaction to finally seeing it would be something other than “yep that’s exactly what I expected”, with the only new information gained being that her knowledge actually does correspond to reality (or at least to her perception of such).
