Poor font rendering..

[Scott Palmer]

If you notice, in the images provided, the length of the rendered text in
pixels is significantly different between the two examples.  That supports
the theory that it is simply, sub-optimal positioning of the glyphs that is
resulting in the more pronounced LCD anti-aliasing.
