Personally, the first oil change from a brand new car would be 3000 mile (5000km). Regardless what the dealer or trip computer might say. My theory behind this is, every engine, no matter how good the build quality, the internal mating surfaces will have some imperfections from brand new. Therefore the first few thousand miles will have them shaved off, smoothed down on their own. The filing will all gone back to the oil (hopefully). But doing that oil change, it get rids of those nasty filings.
Not sure if anyone agrees with me, but that's what I would do.
