Why does my replacement Shimano hollowtech 2 bb have a smaller outside diameter than the old one? From 44 to 41 od. Are the bearings also smaller?

Why

I think it was mostly for aesthetics , so the cups are not bigger than the shell even on steel frames

Are the bearings also smaller?

Yes, but they're still fine, and obviously bigger than internal ones which are also fine.
