The speckling was even worse for me.

By changing the camera to 'perspective' and with location <0,0,-.7>, I see the
nice lemon shape. Also, I don't see any difference re: sturm vs. no sturm.

As an experiment, I negated your spindle function...
      #declare Iso =
      isosurface {
       function {-Spindle (x, y, z)}...

and the interior/exterior textures look correct now. A clue to something?
