The nazis openly destroyed any art that wasn't hyperrealism that glorified the German race.
Impressionism, Cubism, Suprematism, Dada... were considered especially degenerate, even Italian Futurism was deemed "Degenerate Art" which is ironic since most Futurists were nazis or fascists, and Mussolini to an extent welcomed their art.
It was somewhat common for the nazis to kill artists they deemed untermensch and destroy (or keep for themselves) all their legacy, not like our mate here is an artist, so I don't think the nazis would have a second thought about destroying it or be emotionally moved by it.
