The adjuster is just going to work for what they see. Since he's not actually taking anything apart, you can expect that the initial estimate won't cover all the damage if other things are damaged. Once you get it to a shop, they write a more in depth estimate and send that to the insurance company as a supplement. The insurance company will then go through the supplement to make sure everything is in line. Hopefully, with a brand new vehicle you won't have to mess around getting used parts. That doesn't mean you shouldn't scrutinize everything. Best of luck.
