As a former tech I can safely say on my experience no reason to change early. So many never change factory fill until regular oil change interval. I changed all my factory fill out same as interval for particular vehicles. 84 f100 3k, 97 Tacoma at 3k , 97 Corolla 3k, 18 Caravan 4500 miles cause it dropped a qt. and none used oil between changes. At Toyota I have seen multiple people get 300k with 7500 mile interval including factory fill. The only one I know of that requires it is 2020 Corvette as it is a dry sump. Of all engines I have built I never did a shorter interval on rebuild cause I had break-in lube that I used on cranks and cams which most had conventional oil.
