That's funny, because I've actually always felt the opposite. Hoops with matching finish always looked more assembly line cheap to me. A finished shell with, say, hoops of natural wood or an elegant black, have that stately look of the really classic percussion instruments. I'm talking like old school marching band and 18th-19th century drums.
I'm guessing that's why it's trendy at the moment. Vintage, bespoke, custom are all in vogue right now, not to mention obsessions over wood species and over hoop resonance. Making your hoops stand out sort of taps into all of that.
