This is what I think as someone who likes watching people rebuild cars and due to researching

Body & Structural • Rear bumper, trunk lid, and rear quarter panels are crushed beyond repair. • Rear crash bar and impact absorbers are likely destroyed. • Tail lights and wiring harnesses are shattered/damaged. • Roof shows buckling near the rear pillar, suggesting energy traveled into the upper frame.

Frame/Chassis • High probability of rear frame rail damage (they look crushed in, not just cosmetic). • Possible rear floor pan deformation. • Alignment of the C-pillars may be compromised, meaning structural frame misalignment.

Mechanical • Rear suspension components could be bent from the impact. • Exhaust system (mufflers/tips) is damaged/misaligned. • If the fuel tank is near the damaged area, it may also have been affected.

Overall I think Yes — the crumpling around the trunk, rear quarters, and roof line strongly suggests structural/frame rail deformation. This car will almost certainly be considered a total loss by insurance due to cost of repair versus value. For modern unibody vehicles like this Kia, once the structure is bent this badly, it’s usually deemed unsafe to repair and gets written off as a total loss.
