All of this would be virtually accessible. The thing about life on these ships as I see it is that the people will be living on the ships for a long time, even after they begin terraforming a suitable planet - resources will be stretched thin for things like traditional art media. Reading your reply, I get the idea that a majority of art will be done through virtual media; However, pending large-scale demand for a particular artist, they may be given access to some of the remaining materials and allowed to create a physical masterpiece - that would be the ultimate honor for an artist on the interstellar caravan.
