ARKit depth effect for fog or depth of field

Hello,

is it somehow possible to create a depth effect in the AR world? I thought about adding some kind of depth of field or fog to prevent the user of seeing too far on the camera (and game) layer.

e.g. like this:

I'm looking at doing the same kind of thing. Did you find out if fog works with Arkit?
