Any potential negative effects would likely only show in the long run. You can compare it a bit with new brake pads, running on old discs. The pad will have more friction at some diameter positions of the disc, as pad and disc don't wear perfectly even across the surface. If you brake too hard, you will have excessive temperatures at certain araes of the pad and disc, which can change the material characteristics in those areas. The break-in of an engine is there to avoid excessive friction and match the surface of the piston rings to the cylinder walls over time. The 5,500 rpm limit is a recommendation, I doubt there is any harm if you went over the one or the other time.
