My Lightning Blue Raptor has similar issues where you can see yellow shaded primer along the leading edges of most of the body panels. Where the front fenders meet the door panel is the most noticeable area on mine because I see it every time I walk up to it in sunlight. So, I unbolted the front fenders and was able to move them back closer to the door and it hides the yellow areas well enough I suppose. I wouldn't repaint it though unless the clear starts to peel back from the edges. The wheel wells are very yellow as well but doesn't bother me cause that area gets dirty.
Ford's paint booth seems to have issues getting metallic paints to flow onto the edges of the panels. I suppose they are sprayed with the whole truck assembled and its difficult to get paint to flow in the gaped areas between the body panels. Solid paints are probably easier to get into the gaps than metallics.
