Like most answers, it depends.
I agree that the amount of work needed to make an entire scene look as good as you can make a still or a canned animation look, takes an enormous amount of effort, in addition to new software to learn. So I don't see the effort being worth the trouble for a strictly aesthetic purpose.
But in the functional world of healthcare, where I do most of my work, the idea of creating a single bed floor of a new hospital and letting the nurses and doctors take it for a test spin, is very appealing. So I'm about to approach VR from the point of view of design validation instead of aesthetic appeal. Then supplement that simplistic VR with realistic stills or animations for approval of finishes.
There is still a wow factor associated with VR and anything that creates that reaction in a client has a value.
