Look for it under running apps within the developer menu. BK shows it's disabled but it's still running per my screen shot.
EDIT. I'm a simpleton, ones called VR service and other VR services LOL hence one was disabled the other wasn't hence the confused me.

Issue was user error. There are two Google VR services. Ones called Google VR service and the other Google VR services.Just looked, not showing up there if frozen. In fact even if I don't freeze them they don't show up there.
