It's a hard call, and it may be that part of the problem is having a simple-minded idea of what needs to be corrected.

It seems to me that the complaint about over-polished boring music is analogous to the complaint about models photoshopped until they look like plastic.

If a work is just being polished according to a rule rather than because polish makes it better, then it might be smoothed away to nothing. Admittedly, it's a lot harder to see whether a work of art works than whether a car works.
