Black trucks show swirl marks more than any other color. We all expect a new car to be pristine, but that isn't always the case. My 21 Limited came with numerous paint issues and like yours was covered in swirl marks.
I took mine back to the dealer several times. Their body shop fixed all but one issue (including one they caused themselves). I was satisfied with the results. I let the one remaining issue go because in order to fix it they would need to repaint the hood. It was a minor flaw, it just wasn't worth the risk of repainting. The dealer said that if I ever change my mind they'll repaint it any time. I never even notice the flaw anymore.
Don't worry too much about the truck bed. Either have it lined or buy a rubber liner. If you keep it as it is, then it's going to get scratched a lot worse.
Fortunately, these trucks have a deep clearcoat that is polishable. Someone scratched my door quite badly in a parking lot. It was deep enough to catch on a fingernail and looked nasty. I took it to a highly reputable body shop and they said it would need to be repainted at a cost of $1,070. I scheduled an appointment to have it fixed and brought it to the body shop. It was supposed to be ready in three days but I received a call from them later that afternoon saying it was ready. Instead of painting the door, they were able to buff out the scratch. It looked perfect. They said the car had an excellent clear coat, better than most vehicles. They charged me only $150.
If you own a black vehicle you have to be very tolerant about light swirl marks. After I purchased my truck, I took an entire day to detail it and polished out every swirl mark I could find with professional products. It looked great with a deep mirror finish and no remaining marks. Just one year later, the swirl marks are back. I'm extremely careful when washing the truck. I hand wash it myself with the two bucket method, it's never seen a car wash. Yet, the swirl marks come back anyway. The clear coat may be deep, but it's soft and even the slightest things will cause swirl marks. They're easily polished out, but it's a continuing chore.
It's really not worth it unless you're fanatical about having a near-perfect finish all the time. It's a truck after all, not a show car. Even with some swirl marks it still looks great at a reasonable distance unless you're very fussy and are looking very closely.
You are owed an acceptable finish when the vehicle is brand new and your dealer should make it right for you. But expect the swirl marks to come back as you use it. You can get rid of them again, but it becomes more work than what it's worth. Anyone who owns a jet-black vehicle has to deal with this.
