Just so I am not misunderstanding your original post a while back--when you posted:
"Yes xrays will show repairs but in the case of chips drilled through the inlay there are problems reading the xrays. "
That isn't exactly what you meant to say? Now you are saying that yes, you can tell the difference between a genuine, unrepaired one that has been drilled in the center and filled by the manufacturer from a repaired center drilled one?
