Having set up many a P bass pickup, I’d say that the angles in the photos (although quite big) are not beyond reasonable. It depends on the strings, the pickups themselves and the types of magnets/poles/windings as well as fb radius and so forth.
As has already been stated, play it for a bit and see how it is - if one string seems quieter than the others then raise that bit of thebrelevant pickup a bit. The pickup will be seated on springs so turning anti-clockwise on the screw will slowly raise it, clockwise will lower it
