Hello, The following works for me with your example:
#+call: Smx[:exports results](Contents="Interesting") :results drawer latex I am not sure why because I don't really understand the semantics of "drawer" for results and didn't see anything in the docmentation about this option (but also didn't look that hard for it). -- : Eric S Fraga (0xFFFCF67D), Emacs 24.3.1, Org release_8.2.5h-660-gef207f
