Also the VOCALOID4 box seems to say "VOCALOID PROJECT: AKAZA"

I'm assuming the V4 release is AKAZA's voicebank, while the VOCALOID for UNITY voicebank is for "Unity-chan" :/

Seeing as AKAZA's demo uses V4, not VFU, ;/

(Also if thats true, then they DON'T share a voice BANK, but their voices are the same. Hence they're two seperate VBs, even if they sound identical, ones a V2 in unity, ones a full V4 with growl. :/)
