We know that it is possible to use up all your 'mana points' and for your Semblance to stop working if you've been using too heavily for too long. It might be interesting to see what happens if, the next time Emerald tries to spread a hallucination to a large crowd, she burns out her Semblance and suddenly everyone can see what's really happening.

I wouldn't be surprised if that happens at some later point in the show.
