Specular higlights are view dependent and the specular higlights seem to react properly when tumbling the virtual camera. It seems reasonable that it would be possible to do a reverse calculation to determine the location and intensity of light sources in a scanned scene. Once those are determined, they can be extracted from the scene and made global light objects in a scene in a DCC app or game engine. More than likely it would just be baked as one big IBL dome light.

I could be wrong about all of that though.
