Ha! I remember how disappointed I was years ago, when my new bore-scope didn't reveal all the secrets of the rifle universe.

Probably the best use I've gotten out of mine is seeing how well various bore-cleaning products work. But even that doesn't predict how well a barrel will shoot. Some of them love being dirty....
