This isn't that complicated. From your original post:
> If I go with a friend who understands the context, they can explain to me the history
Either your friend's explanation improved your experience at that museum/gallery, in which case I say "Put it on a plaque", or it didn't because our understanding of art can't be improved by any kind of brief explanation and really you need to "take an art history class" as you directed us to do. So which is it?
My conclusion is this: if including any kind of explanation --short, long, anything-- can improve the average person's experience at a museum or gallery, then they should do so. The fact that they don't makes a lot of people skeptical about the entire thing, which is a shame.
