The car has no idea what oil you put in it. The OCI indicator is based on throttle input, load, operating and ambient temperatures, plus some other odds n ends. Synthetic or non has no bearing on the interval as far as the OBC is concerned.
Also, a visual observation (dirty, clean) doesn't mean the oil is of any particular condition.

There is no dyno or track time on any new car we can afford. Anyway, sure there is some gear mating and a tiny bit of ring seating but todays engines are not built in barns. It's not like there are CNC shavings sitting in the valve train. Most contaminants are from the casting process but get easily trapped by the filter.
I also change new engine oil early, but after that per the FSM. Considering the big diesels go 20k on one change and the oil is within spec...
