Frames should be plumb (2 directions) and head and sill level. But reading bubbles is not as good as measuring the diagonals. There isn't much you can do with the frame anyway. The door fits the frame, not the other way around.

Look at that light gap on the leading edge, not the hinge edge. The door will be slightly ajar. You checked the top gap, I'm sure you've looked at the bottom gap. When it comes to door and gates, gravity wins every time. I had a friend that did a lot of gates and he hung them out of adjustment every time. They were high on the leading edge. 2 weeks and they settled to perfect.
