I'm not sure you understand what I'm trying to say -- or, for that matter, what pjeby was trying to say. Notice how I never used the word "qualia"? That's because I'm trying to avoid becoming entangled in issues surrounding the reduction of qualia; instead, I'm examining the results of Mary's room given two mutually exclusive possible assumptions -- that such a reduction exists or that it doesn't -- and pointing out that the thought experiment generates results consistent with known physics in either case, provided we keep that assumption consistent within it. That doesn't reduce qualia as traditionally conceived to known physics, but it does demonstrate that Mary's room doesn't provide evidence either way.
