All repair paint jobs require blending in with the adjacent panels it's just part of the refinish process. My friend has his front fender repaired at MS Auto and it took them like 4 tries to get it right.
When my old man sold Acuras back in the 90's for the Royfoss Group he did mention that not every dealership have their own body shop, and that dealership owned body shops are usually the best quality with access to OEM stuff (maybe bias since he sold the most NSX each year and their body shop had to spray new NSX replacement panels from time to time). But $1900 to respray just the front bumper only does sound steep to me.
I've heard before that DVP North is owned by an entity in Japan, most likely emphasize on quality work.
