Damage? probably not.
Logged over-rev on the ECU? probably, but I'm not sure how the stock ECU works, may or may not be able to be wiped.

Best to have independent shop check it out, and then try to find out if there's a counter in the ECU for these things. If there is a counter, try to see if you can reset it. Worst case, engine warranty just went poof.
