Is there a visible difference looking at the wheel between an OEM Cup 1 and a replica. The wheels I'm looking at have 7 and 55, and 9 and 55 by the valves.

 
Yes those are OEM, you won't find those offsets on the MM reps.

In the pic below the front is OEM and the rear is a rep. Look closely and you'll see that the spokes are a little more curvy on the OEM.

The internal corner radii where the spokes join the rim are more generous, and they are a shade darker on originals.
 
I would have thought it difficult to tell from that photo. The rims differ front to back any way due to the fact that they are different width wheels. The best indication is the offset number as has been pointed out by the valve, aswell as the complete Porsche part number behind one of the spokes. Someone with 17" cups should be able to provide you with that [;)] i only had 16" unfortunately.
