Can someone please post a picture of the holes left after removing their splash guards? Thanks in advance.

 

just put the screws back in - you dont see them unless you're sticking your head in the wheel well or crawing around underneath. geez

 

If your splash guards have been on for a while, you may have some scratches/discoloration on that area when you remove them. But as far as the holes, falzpozitive is right, just replace the screws and you'll never notice them.
