I would argue no, because those frescos are littered with deep symbology and meaning that are being assembled in one work. The art is in the beauty of the work, the story it tells and what it represents.
I worked for a long time around 1960s/1970s abstract art. Much of it was of questionable quality in my eyes, but there are some really amazing pieces that really make for amazing and beautiful spaces.
My beef with the abstract stuff is that it seems to cut off the oxygen for everything else. Art is fashion, and the patrons of art tend to be fashionable people.
