Listen to me buddy. You are obsessing. The pics seems different but the difference is so small that I can't really tell if you are balding, maturing or whatever. With this small changes or at this probably intial stage of hair loss OR maturing I can't tell anything. You seek certainties on an internet forum sending pics... that's not how male pattern baldness can be diagnosed, it's not obvius in your case. Do you want a correct answer? Logout from this forum and go to a good dermatologist specialized in hair, with a videodermoscopy he can see your density and if there are miniaturizing hair over the scalp.
