Didn't apple just release a VR headset with 4k displays for each eye?

Yes but those displays are stretched over a much wider field of view. When I sit on my couch and look at my TV it is covering maybe 30 degrees of my FOV. A VR headset typically would like to have 100+ degree FOV, which means a 4K VR display will have way less fidelity than a 4K TV.

Right, but presumably you would need insane pixel density to achieve 4K at that range?
