It looks to me like the supplement is D3 and the one you get from UV exposure is D3, so no, spending time outdoors doesn't give you any better Vitamin D than the supplement. Of course, exercise has other benefits.

I would amend that to no proven benefits. The body is a complex system. D3 generated by the body via natural pathways may be more effective than ingested D3 in some way we don't understand yet.

Leaving aside any other ill-understood benefits of sun exposure.
