You said it perfectly, Leonore, "Pure unadulterated enjoyment."
I agree with everything you said, including your analysis of "Columbo Goes to College."

The smile at the end shown as Keppel's enjoyment that he was caught with his own methods was not consistent with the character up to that point.
As to the quirky, crazed smile at the end of "Double Exposure," I viewed it as his character totally cracking - mentally. Up to this point, Dr. Keppel always thought he was in charge - the far superior intellect in this cat-&-mouse game - with enough confidence and arrogance to toy and bait Columbo on his own ground.
..... and when he lost - he lost "it"!
Have you ever seen the unaired pilot "Now Is Tomorrow" (1958) ... it's comes up on now and again on eBay and i-offer ... (it's also on the TCM site, but more expensive there ...)

It stars a very young Culp, but has a very similar ending scene to "Double Exposure" - though played far broader. If you haven't seen it, try to get a copy, you
will enjoy it.
All my best,
