IMO, not quite. There is a further word that needs to be
included--"consciously" (between "be" and "perceived").

And since the unconscious mind does far more with input than the
conscious mind, it is entirely possible that the unconscious mind can
sense that something is missing and not be able to tell the conscious
mind exactly what it is.


You are missing the point. The observation that I made is not a
defense of perceptual coding but rather why George's demonstration of
taking the difference between a perceptually encoded file and the
original file is bogus. His "amazing" demonstration to "audio
professionals" indicates that he does not understand the basis for
perceptual encoding or he was deliberately misleading the audience.
This also does not say much about the technical competence of the
audience.
