In your beach reference the skin looks "oiled"/wet. This is typical and believable in such a scene.
Anthons picture shows an indoor scene. We recognize this because there is no sky. So we don't await hard shadows, because we know skin isn't only lit by the sun (direct light mixed with indirect light resulting in soft shadows and wide highlights). Something our brain recognizes automatically.

It isn't possible to have one single type of shaders for any light setting. But something to select different light-response types and/or environments with one click may satisfy most needs.
