So I did a bit more checking. It is actually the highlights slider that does it - contrast just makes it more obvious. It is as if the highlights "masking" is getting created in the pre-transformed data and then distorted in some way when going through and extreme LCP like with a fish-eye. Here is an example, contrast at 100 and the "Strong Contrast" tone curve used in both. The one of the left has highlights at 100. Notice the "shadows" in the sky of the leaves, as if the mask was somehow stretched differently from the image data. This was with a fisheye lens and fisheye LCP. You can actually recreate the problem to a degree yourself with any image. Just apply any of the fisheye lens profiles from Adobe (Nikon 10.5mm for example) and look at high contrast regions near the edges of the frame with highlights set to 100%. You'll see shadows like this (again, easier to see with extreme contrast settings). Without an extreme profile applied no such effect.
