Now that I think about it, due to this cognitive architecture issue, she actually does gain new information. If she sees a red apple in the future, she can know that it’s red (because it produces the same qualia as the first red apple), whereas she might be confused about the color if she hadn’t seen the first apple.
I think I got confused because, while she does learn something upon seeing the first red apple, it isn’t the naive “red wavelengths are red-quale”, it’s more like “the neurons that detect red wavelengths got wired and associated with the abstract concept of red wavelengths.” Which is still, effectively, new information to Mary-the-cognitive-system, given limitations in human mental architecture.
That does seem right, actually.
