Only your own trend analysis will inform you if the engine is doing well or wear is increasing. Two samples just not enough and different intervals. Other that multiple samples UOA is pretty useless IMO . Now if you want to really have great wear numbers just change the oil every 1000 miles. You increased the OCI and wear numbers went up as expected, question is due to wear or just a longer OCI. Probably never know, too many variables which is why, IMO, UOA is a waste of money. I threw a ton away on these years ago, now, who cares, other than coolant leaks etc not much one can do about a bad UOA report etc worry about it. Good for discussions though.
