I assumed the self leveling led whatever wonder-tech-wizz cannot be aimed. If they can, that should be the first reaction of someone who is getting flashed at a lot. As opposed to flashing back. It's not a headlight-measuring-contest.

But if it's a newish car, I assume it is factory tuned to whatever standard it is supposed to be, and if you change it, at the very least it will get changed back when doing MOT.
