Jay, on my 2013 that trim is also aluminum. You could try to use a wooden mallet or a hammer to gently tap it down towards the wall or at least get it closer to the wall. If you use a hammer, place a piece of wood to cover the trim so you don't damage the trim with lots of dents. If you can get it pretty close, I'd use some sealant to fill any gap left. Be aware that you could lift the roof side of the trim piece when your trying to push down and straighen the wall side. Go slow and be as gentle as possible.
I'd also be concerned that you have an unseen crack or break in the caulk or eternabond that would allow water to get into the roof and wall area. I would do a very slow and thorough inspection of the damaged edge all the way down. It doesn't take much of an opening to allow water to get into the roof or wall and cause you more headache than you want. Good luck
