While a VRDisplay is blurred it does not lose it’s presenting status (VRDisplay.isPresenting continues to report true) but VRDisplay.getFrameData() returns false without updating the provided VRFrameData and VRDisplay.getPose() returns a VRPose with null members.

The event object is of type VRDisplayEvent.
