It looks like you've created images similar to the reviews of the lens from both www.the-digital-picture.com and www.kenrockwell.com, particularly the angled view at a wide aperture in Rockwell's post. Both reviews comment on using Canon's lens profiles in DPPv4, where the correction is possible, but not perfect. Avoiding the angle, light and aperture setting is probably most effective.
You are correct. There is an image of a watch in the Ken Rockwell review that shows blue tick marks on the left and brown tick marks on the right.
Thanks for everyone's help on this. I thought I had a bad lens and/or camera. Now I realize it's just me. :) And according to Scotty - the laws of physics.
