No this is not correct , We have tested both 3G voice and VoLTE over AT&T network in USA and found the difference between 3G and VoLTE to vary not by a huge margin ( 8.5 on Volte vs 10 on 3G).
Once the VoLTE call client gets integrated into the modem and we can use shorter DRX cycles then the difference will disappear.
