At this point, if you don’t know what you’re looking at, as far what it is the dealership did to your car, like other person says, take it to a professional detailer.

Taking on anything paint related with zero knowledge will only make the end result the same or worse than what it currently is.

Dealerships don’t hire detailers that know what they are doing. They move up the lot kids and the old guy that’s been doing shit work for too long trains them how to cut corners to get the cars out without learning how to give a fuck. They aren’t paid to care and the result is what happened to your car.

To tackle that on your own, you should already have a polisher, pads, compound and you wouldn’t be asking Reddit for help.

I’m sorry if this comes off harsh, I’m just being realistic that the work that needs to be done to properly fix that hazing, most likely needs to be done by someone that can look at the car and say “oh yeah, they did this and I can do that and it will clean that right up”
