TLDR> Basically, we just need to "KNOW" where these IIIF manifests are hidden and catalog them.

One of our fixtures is this record, with no static image or IIIF viewer:
https://geo.btaa.org/catalog/018b1db0-726a-4727-af0a-5c7e18783ace

It's from the U of Chicago, which uses LUNA as it's IIIF server:

Under the SHARE feature there, they have a link to their IIIF Manifest:
