It's hard to make a door bow out and not have a ripple in the metal that the eye wouldn't see. Also the door edge (the skin) is not far from the door frame which supports the edge. Any movement out on the edge would leave a wrinkle and maybe crack the paint. I took the posted picture and tilted the image 5 degrees then cropped it. Enlarged to 150% of original. Added a thin red straight line. The cowl is almost flat at the red line which may indicate a cowl problem.
I think it's common knowledge that when the old hinges rust up, forcing the door to open can bend the cowl in. Later on, if a dent occurred, it may be hard to tell where the problem lies.
