How are you actually defining "new" here? Have you considered that you are defining "new" in an amorphous way that allows you to reject everything new that VR/AR offer?
AR allows one to create virtual objects with actual position and shape in the real world. We can see these objects in their location in the world, and interact with them. That is the abstracted case of what is truly new -- the thing that simply does not exist without AR.
From this abstract case, we can give concrete examples. When buying products online, one can discover what furniture will look like in their house, or what clothing will look like on their body -- they can better see it from every angle and the form it will take. In terms of "adult entertainment", one can literally experience a virtual person up in your face and on your body, something that is just not offered by any existing form. Shit, we can attach a virtual note to a physical object (that only select people get to see!), we can use a ping pong table without needing to own a ball, we can see "subtitles" next to a person who is talking, we can see a label next to our friend in a crowded place without having to constantly cross-reference a map on a phone screen... honestly. Have some imagination.
If you can see this list of things and say "none of that is new", then I seriously challenge you to define "new" for me, because I'm willing to bet you are not applying the same rigorous definition to smartphones.
