I don't think anyone here will claim that art is about realism. And I think "indulging in a perceptual experience" is an absolutely brilliant definition of art.
The problem is that a lot of modern art, which includes some of the pieces in TFA, fails that definition as well because it relies too much on insider context. Art that is designed to be "understood" in a way that requires a 5-page explanation to someone not familiar with ideas and trends known only to people in the modern art industry is not a "perceptual experience", it's a riddle game with a very limited target audience.
Truly great art may have such aspects as well, but they take a backseat of the "perceptual experience" aspect, which makes it recognizable as art to almost everyone, even of they don't understand everything the artist did.
