You can spend a few dollars and send the oil sample out for analysis, but I don't think it would show much that is good. This is a new engine and you should expect some wear of the bearings and mating surfaces, just as you would have with any new engine. The first oil analysis should show a higher amount of metals, etc, in the oil.
Personally, I would just change the oil and enjoy the coach. I didn't worry about the person(s) who put the delivery mileage on my coach when it was being sent from the factory to the dealer. I had to trust that it was driven right for the first 3500 miles. Now 80,000+ miles later, the engine still purrs so I guess no harm was done. :B
