What I meant was, lets say you and Zhang Ge both sit in front of a bunch of grapes on the table, what he sees before he start paiting them is different than what you see. And after he finishes his "photorealistic" painting, what you see from the painting is different than what a pair of trained eyes see.
My point is both a piece of art and its realistical counterpart have different meanings to different people, so to cite Wilde's words to support your personal taste is naitive.
