The Importance of Density Matrixes in Art

For the universe as a whole, should we think of it in terms of the pure state of wave function or a density matrix? The thing is that for the thing about density matrices is there's no experimental difference. My own art style favorites have been evolving, I think, a little bit with time. For a long time, just regular old abstract art was my favorite,. which in some sense is minimal. But Jackson Pollock or Mark Rothko are not going to have a lot of tiny, small-scale details.
