I think my attempt to "clean up" the scan may have actually exagerated the sun damage. There is definately a difference in the color of the inlay...and probably due to light damage. Here is a different side-by-side. In this one, I didn't touch the scan at all. This is straight from the V30.

Looking at the camels compared to everything else it seems hard to believe that the camel would fade so much...yet the other colors appear to be unaffected for the most part. In addition, the actual shades of the camels matches almost exactly (at least as much as you can tell from scans) to the two shades on the known $1 variation. (scan 2)
