what is the use of having a video call where you have hunders of people seen each other?? even with a 4k display you cannot display more than couple dozen people at time.. more the a couple dozen the videos get so small they are useless, at this point it is better just go audio.. usually you are only interested in the video from a couple of people and usually one at time.. and software we have today can already handle it with connections below 100mb.. i dont think you need that much for VR.. you probably can get good realistic vr with 1gb.. the last two are specific needs for specific fields, i hard say it is something that fall under consumers needs
