Based on those pics, it looks like the rear body panel got pushed in just a bit which is causing the decklid not to seat square with the quarters. Can you pull up the carpet inside the trunk and see how the floor and the frame rails look?
(My daily grind is a field adjuster for a major insurer...which is why I ask).
Took a look under the carpet and except for the bolts on each side being pushed through didn't really see any other damage to the rails. I'm certainly not an expert though.
everything should be better view if you take out the bumper... but honestly it doesnt look like it had enough impact to bend any frames of your vehicle...
hope everything works out well for you
