Something like the following should work.

#+call: disc[:file (if (and (boundp org-export-current-backend) (equal org-export-current-backend 'html)) "foo.svg" "foo.tex")]() :results file

And you could wrap up the extra-long Emacs-lisp in a function or macro
in your init to avoid the overlength header argument.
