Halogen lamps have cut-offs pretty much like HID projectors. Judging from the pics you posted, you definitely have some improved foreground lighting. With a better camera and wall pics, we'd see the projection and cut off you are getting - that is, if it's not offensive to oncoming drivers. I would suspect that more modern vehicles that are not equipped with HID lights use adaptive optics for a conversion. HID lights do not necessarily demand projector optics, hence there are two HID bulb types - one for projector type housing and the other for HID reflector housing.
