Unless Leica has hit upon the solution for teleportation, someone/something had to physically move the lens (in its package) to get it from the Leica factory to wherever you were when you inspected the lens, which means it was quite possibly subject to jolts along this journey and, since AFAIK Leica lenses are not hermetically sealed, variations in temperate and air pressure. These two conditions alone, along with the myriad of variables such as exact quality of those exact packaging materials, the route taken, the weather, the exact qualities of the lens and conditions affecting its manufacturing, etc. ad nauseum mean that just about anything could have given rise to the specks you notice. My point is that there is no reason to automatically suspect lapses in Leica QC because you find deviations from theoretical perfection in a "new" lens. The world is a vast, dynamic place, and with limited empirical data and theoretical understanding (a sample of two and little or no knowledge of the exact circumstances surrounding manufacturing, QC, and transportation) you're just not in a very good position to say much about correlation, let alone causality, within it.
