Thanks for digging deeper.

That was Laurens' original command but I found the convert(1) here
sticks an ASCII NUL after the title, which pdfinfo pipes to grep which
stops the dimensions being extracted by gropdf.
$ convert map.png map.pdf
$ pdfinfo map.pdf | sed -n l
→ Title: map\000$

That's why I moved from convert(1) to gm(1) only to hit a new problem.
