Remember that those are not 72 distinct frames per eye per second. Each frame is "flashed" three times, then the next "moment in time" comes on. I would be surprised if the file was encoded at 72fps per eye. It is likely 24fps and the hardware shows 72fps, just like 72hz capable TVs or a three bladed shutter in a film projector. It would seem inefficient to me to encode it at 72fps per eye, as that would be wasting space... but then again those d-cinema guys probably don't realize that.
