Was my standing seam roof installed properly?

Hi - I'm in the process of having a standing-seam hidden fastener system (Ideal Junior HF) installed by a contractor on our garage. The attached photo shows a couple of areas that I'm not sure have been done correctly. He's told me this is "just how things are done", so I w would value some advice and opinions from other installers:

1. Ridge cap: in the area where the pitch of our roof changes for the shed dormer, you can see that the ridge cap is bent up to accommodate the different angle. Its a vented ridge, so there is mesh underneath - I'm not so much worried about things getting in as I am that it is unsightly. He says it is the only waterproof solution. I suggested cutting a slit in the ridge cap at the transition point so it could lay flat, but he says this would let water in. Thoughts?

2. Some of the panels are bowed up. He says the panels can do this in cold weather and it will sit flush on the roof deck in summer, but it seems like a big opening for either driving rain or insects to get into.

3. Exposed ends of seams (and panels for that matter) Are these typically capped or sealed, or left open as in the photo (again, it seems like an entry for pests) and moisture).

Thanks in advance for any insights.
