Perhaps much of this discussion is based on the reality that no two people see exactly the same way. Much of what we see is because of processing in the brain and not based solely on what is presented to the retina by the lens.
My mother once commented about a professionally produced portrait of my sister something to the effect that the professional photographer tried to make the person--subject of the photo--something like she wasn't. It was an astute observation that a flattering portrayal is not always accurate to the subject. I understood her thoughts. In that sense, the professional portrait, though very nicely executed, was not a good portrait of my sister--it didn't look very much like her.
