Dear Matthias,
my background is in humanities. This is why I see that tagging is
lacking language (for mixed-languages documents 😅).
I wonder whether it would make sense to replace your label with:
{\externalfigure[cow][label={A cow, contemplating}]
{\blank[-3st]\color[white]{$e^{\pi i}+1=0$}}} % path
Of course, full transparent text would make sense with other backgrounds
(either from the page or the image itself).
As for tagging, reading the info with https://ngpdf.com alternative text
seems fine to me (but I cannot speak for software readers).
Just in case it may help,
Pablo
