I'm not sure I'd necessarily consider that article to be the only definitive source of information.
It's worth pointing out that it isn't unknown for VoLTE to work on unapproved devices, e.g. the unbranded S7 edge which works on 3's VoLTE (you do not need the 3 firmware installed, or to buy the phone from 3)
