Modern engines are engineered and built so that the "metal shavings" bit which existed with engines in the past has been pretty much eliminated. In any event, any "shavings" which could negatively affect a new engine are removed by the oil filter. In the old days oil filters generally were the bypass type, which didn't filter all of the oil being circulated to engine bearings, etc. by the oil pump, but modern filters are full-flow - all of the oil being circulated by the oil pump has to flow through the filter.
I did my own oil change at 3,000 miles. The oil looked great and I took a good looked at the filter and I saw nothing in it. If I had to do it all over again, I would just wait until 10k. But since I am old school, it did make me fell better.
