Well done with the effort. Id say no one will even notice the issues unless you point them out or they are inspecting it.
I have been involved in getting commercial vehicles "vinyl wrapped" in the past. (Note: Not saying it is the same stuff but is subject to similar installation issues etc).There was always some issues. Air in concave areas, no matter how much it was pushed, eventually our heat made it try to take up its flat profile, dust under the film. Even when done in dust filtered paint booths there was always some. Stretch marks and bubbles that showed up when certain angles of the sun hit the vehicles.. Dulling of the surface, esp if colored....:( You're right re darker, mat colors, etc being more forgiving. Does work well to protect the original paint though esp from stone chips.
