In the second generation Prius, they put the boost converter in the front so much of the advantage was lost. If I were to design it, I would put the boost converter near the battery. (Not sure about the third generation, though.)
I think one of the main advantages is that the supply voltage can be varied so the inverter can output more precise waveforms at low speeds. Digital audio amplifiers are remarkably similar to sine wave inverters and they often make use of dynamic supply voltage to maintain their specified bit depth at low volume settings as well as to reduce switching losses.
