To complicate things, there used to be a theory that the factory oil fill had additional additives to allow for initial breaking in. I really have no idea if this was ever true, if it still holds today, and what the impact of it would be...
I've been running interim oil changes, except this last two years, when mileage was virtually nothing. Still 13,000 miles showing when oil was changed. My dealer did it for about £155.

Interesting comment on the additional additives, not seen any data on this subject for recent BMW engines.

When I was running VW back around 2000, I was wanting an early oil change for a new Passat PD TDi. Dealer showed me a data sheet, where VW clearly stated, not to change the oil early, as it was filled with a break-in oil.
