Im pretty sure my friend had a screen protector capable of this more than a decade ago, but I am curious how they’re able to implement this in software rather than some physical method.
I’d hope it’s more that that because this wouldn’t give you any “privacy” as someone next to you could read it if you were actively using the device. The old screen protectors had little ridges that blocked the light from escaping to the side so you could only see it straight on.

Maybe its similar to amd where it uses the camera to see where your eye is looking and only display that area?
I’m assuming it simply darkens the screen when it’s not directly facing you:
