Digital Photo Professional 3.0.2 preview problem

I’ve updated Digital Photo Professional Preview Inaccuracy to show that the same (or worse) problem still exists with version 3.0.2. It’s maddening—I was hoping to use Canon’s EOS Utility to check critical focus for a series of shots for my upcoming Zeiss ZF lens review, but alas the defective preview still exists.
