One major difference between VR and AR content is that VR can do blacks. Current AR is limited to overlaying more light onto a piece of your visual field. It has no way to make any spot more dark. This is fine for VR, since there should be no other light leaking in apart from what is produced by the unit. AR at the least needs a projector that can compete with the amount of light in the your scene already.

You could make an occlusion shutter but I haven’t seen a small lcd with the requisite speed and resolution.

You actually can't do that: People have tried, but the plane of focus makes the LCD too blurry. It's an unsolved technology problem.

So the whole light field techbuzz was just vaporware hype? Or no, but even that can't do black?

Actually, my understanding is that light field is actually the ONLY way you could have ar with opaque black. However, you'd need orders of magnitude better light field tech than what's available.
