The subpixel smoothing isn't being used. This trend dates back to the Zune desktop software, followed by Windows Phone 7. A theory puts emphasis on how the “Metro rendering engine” works. Because Metro puts a lot of emphasis on animations and transitions, the ClearType technology never played well with text moving, changing size or rendered against a transparent surface.
