Wait. I'm not dismissing you rhypothesis, just pointing some possible flaws. First, Gyo, as usually employed, lets the user see aura hidden with In, but does not seem to enhance their sight. Besdies, photografic memory is different from plain sight. As for Neferpitou, it would be useful if you specified the chapter, but he has used Specialization and Manipulation on his puppets. The idea of enhancing someone else seems to have little to do with Reinforcement.
