Looking at Image1:
The Artifact parent is S:Worksheet, but the K entry for Worksheet does
not contain the Artifact. From this, I infer that the Artifact does not
appear in the page content stream.
Note that each Artifact (which is RoleMap Sect) is followed by an entry
of type P, which is in a TextBox. The TextBox entries do appear in the
Worksheet list. Without digging through all the content streams, I would
hazard a guess that these are placeholder entries for Alternate Text,
which were not used. At this point I'd put it down to an error in Excel
export.

Huge thanks Tilman
I’m still learning this stuff. But I did debug the loading of the image PDF,
paying close attention to the structure tree. The more I dug in, the more I
started to think this was a PDF output issue from Excel. But the spec is
large, complex, and obscure in places. So I was still uncertain.
The Cross Reference table view in the PDFDebugger fairly plainly shows
StructTreeRoot, ParentTree (in StructTreeRoot) and page content. And it’s
plain there’s discrepancies. Allowable by the spec? No idea.
