Is it possible to glean the input voltage from Apple TV?

This is a very hacky question. I'm traveling abroad and failed to bring my trusty multimeter with me. Chile operates at 220V and most outlets are the round prong European style. But there is a single unlabeled outlet in the apartment where I'm staying that is a hybrid American and European style (it accommodates both round and straight prongs). I'm assuming that it still pumps out 220V, but I'd like to find out for sure.

I have a third generation Apple TV with me, which I know can take 100-240V. Is there a software-accessible diagnostic in its guts that will tell me the actual voltage input it is receiving at any given moment?
