How to know if "disableInitialLoad" was called on GPT?

I need to know if googletag.pubads().disableInitialLoad() was called, in which case I'll load and ad using a display and a refresh calls, otherwise I'll load it using just display. My assumption is that if I always call display plus refresh I will get to ad requests unless disableInitialLoad had been called.

Is it possible to know that?
