OK, as promised.
On Nov 16, I said, "I'll endeavor to get some scans of the new Deluxe single-frame cap code when I next run across it. That probably won't be for a couple weeks..."
Here you go (just a gif for now, but it's clear enough): 
This is from R2 of Once Upon a Time In Mexico, and is an example of the new Deluxe CAP code (aka "CRAP" code, by some). Printed at Deluxe Hollywood. This is an anamorphic movie, so you'd need to stretch x2 to understand the full visual effect.
Note that this was two consecutive frames long, different from the old Kodak CAP code (1 frame), the earlier versions of the new Deluxe CAP code (1 frame), or the new TES cap code (3 frames). (Perhaps frame numbers are/were variable, I don't have good data on that).
It does stand to reason that multi-frame CAP codes are harder to defeat, since they will show up better in frame-by-frame compression algorithms, and will defeat CAP code (and dirt) removal algorithms that try to remove single-frame high-contrast small elements.
If anyone has the patience or proper tools (editting -style viewer, I suppose), I'd be interested if there's data on how many frames long the new Deluxe and TES cap codes are, beyond my limitted dataset.
