The fresnel highlights also make sunrise / sunset look better. Here's a stormy path, but, since we're facing the sun, the "world sphere" highlight brightens all the scenery, and the "frosted tips" highlight enhances the peaks of hills, bumps, and even the rocks in the road. The ground and plants add in with their "Sunny Trail" specular, helps highlight the center lighting of the scene more. It's a lot of "death of a thousand cuts" improvements, but they all blend together to enhance the overall result.
