VR and AR have essentially merged at this point. Nobody is releasing VR headsets without passthrough (and non-passthrough VR still isn't viable tech yet. cost, brightness and poor FOV are holding it back).
Passthrough AR inherently has the same FoV as VR so I'm having trouble interpreting your comment. I also don't see how brightness would be an issue for non-passthrough VR. Did you mean "non-passthrough AR", like the HoloLens?
In corporate there are bunch of neat areas but AR is defintely more useful right now. E.g. support, meetings, teaching
