Ok that's what I thought.
I had a long discussion on Twitter and requested they specifically check the whole route, both as KL/DL/DL flight numbers, and as KL/KL/KL flight numbers. In the second case with all KLM flight numbers, they can see Z availability on the AMS-DTW flight operated by DL, but still nothing on CPT-AMS, even though that flight shows Z9 in EF.
And another wrinkle now they noted is that the CPT-AMS flight is already in my ticket with the KLM flight number, rather than the DL code-share I purchased. I guess this got changed when they upgraded the outbound flights. So now they say it's not upgrade-eligible since it's a KLM-coded flight not booked in Y/B/M, and they seem unable to move it back to the DL flight number. Hopefully if/when Z space appears that they can see, they can find someone to override the rule, since I purchased it initially as the DL code-share.
