I think you are fooling yourself if you think that art has anything to do with ultimate reality. Because tell me now, what is ultimate reality? You have no more than a hunch, which is destined to be wrong, because the basis of this hunch would just be a giant mess of human perception. And human perception has nothing to do with ultimate truth and reality, merely with conventional truth and reality. Ultimate truth is not explainable in words, nor comprehendable as a conventional concept.
Art is merely the manifestation of the will to be, or in other words: a manifestation of self. It is human nature to create and explore, because it believes that there is a self that creation will do something good for the self.
You can't argue that somebodies answer to the initial question is either wrong or right, unless flawed logic is used.
