Note that using M-: will always hide any (message "foo") might have
been called because M-: outputs the return value of the function.
Usually you can recover those by inspecting the *Messages* buffer, but
in this case org uses org-unlogged-message so you can't see it there
either.

Try this :
M-: (prog1 (org-display-outline-path) (sit-for 2)) RET
It shows the message (for up to 2 seconds), and then it is hidden by the
return value (a string with properties) when the call to M-: terminates.
