Check near the chainstay for paint chipping (or anyplace it chipped) to check for original color not matching topcoat. Also, you can check near lugs to see how crisp the lines are. You should google a guess at a mid-80's Super and see what comes up on "images". You may see something similar.

And +1 to what CliffordK said.

ETA: It's my inclination to believe it is NOT a repaint. The paint scheme is quite complex to duplicate even though I didnt see anything like this on the internet after a short search. Look at the dropout pic, the fade has a factory/shop professional look to it. If it's a repaint, I certainly cant determine from this set of pics. I love the double clubs panto on top of the BB shell.
