One more thing... I didn't actually attempt to answer the question you posed: "Is improvisational jazz to impressionism art as smooth jazz is to realism art?"
Realism is not monolithic. Nor is abstraction.
Compare a newspaper photo to a photo by Edward Weston.
They are arguably equally "realistic" yet what they convey varies enormously.
I'd suggest that what's most helpful in the end is what Louis Armstrong said: "There is two kinds of music; the good and the bad".
If we remember this, it can help us avoid getting too hung up on what's most naturally appealing to us and keep us focused instead upon what's being communicated and the skill/invention that's on display, whatever the style.
Needless to say, this is often difficult!
