Can’t help but think of the 2002 Ted Chiang novelette “Liking What You See” and its tech “Calliagnosia,” a medical procedure that eliminates a person’s ability to perceive beauty. Excellent read (as are almost all his stories, imho).
Don't know about that - but we're incredibly sensitive to some minor changes to faces;
I saw a clip not too long ago of a face digitally transitioning between male and female, the changes themselves were incredibly subtle, and yet the result was obvious and undeniable.
There's also the uncanny valley, faces that are almost human yet very slightly off, and somehow come across as incredibly creepy.
Experiments have shown that we perceive our own face as more attractive than it really is. When presented with a series of morphed pictures of their own face, from less attractive to more attractive, people tend to not pick the unmodified picture as the real one, but one morphed slightly more towards attractive (where “attractive” mostly means “symmetric”, IIRC).
