It might be difference due to technologies. The older one likely use "white" lamp and color filters over CCD array. New cheaper approach is a line of red, green, and blue LEDs that are flashing in sequence. In both cases color pixels are spatially separated, but perhaps there is some difference in post-processing. I have seen mostly black and white text scanned with color pixels on the edges of each character. Blurring might be an attempt to mitigate this effect.
