My bike was the same way when I purchased it. I told them I wanted it fixed before I took it. I believe they simply loosened some bolt and used force to make them straight and retightened. It was out by at least 5 degrees.
I totaled my front end by hitting a deer on the way to work last November. They replaced everything including the triple tree. It was the first thing I looked at when I picked up the bike. Maybe they remembered how analysis I was about it. You can really see it when riding.
It's amazing how many handlebars I've had to adjust. None of them are straight. And the real reason why? They come in a crate to the dealer and a teenage kid making minimum wage then puts on the handlebars and accessories. Hard to get handlebars or driving lights straight when you don't care and your texting your friends.
They are easy to adjust. Take the top plate off and loosen the riser bolts. Use something like a broom handle to line up the risers where you want them. If you don't the bars will just keep going back to the same place every time you tighten them up.
Give this a try, look at them with your left eye closed, then with the right eye closed. Mine look the same but just slightly. Turned out to be an optical illusion through my dominant eye.
