Not far off being perfect
I suspect that the image of the hat-shelf when the boot is open (either incomplete roof opening or traditionally) will show the rest of this.
If the flap is up any more, then adjustment of the cable (and probably the wheels) is needed. If the flap stays in teh same (relative) position, then the hinge and its rubber stop (or if you have it, the rubber stop beside the pulley) will need adjusting.
There is also the option of improving the hinge line, so that there are almost no gaps each side of the hinges, but yours is (again) almost perfect.
And then the line of the main shelf (as it touches the boot) is controlled by those two bolts, which touch the edge of the metal hinge that the shelf itself is mounted on. (Unfortunately, there is very little extra mounting area or contact area around that bolt, so the idea of mounting one of those soft-close dampers from a kitchen drawer becomes unwieldy)
I'll get some pictures of mine (which I now hope will validate my comments) and then I can check how much room the hat-shelf has to avoid contact with the roof.
