My guess is that the Leica lenses control internal reflections to a greater degree than the "Brand N" lenses. According to this theory the shadows are not fogged by scattered reflected light; the deepest shadows are darker and the subtle details in those areas are not obscured by fog. I found it hard to explain the differences just by looking at the slides but once I had high-resolution scans and Photoshop the difference was obvious.
