The Note models have an added screen protector on top of the glass screen for better writing feel. That reduces contrast and sharpness somewhat. Both Kit and Voya (My Deep Guide on Youtube) have mentioned that in earlier videos.
According to the latter the reduced sharpness was an improvement for Kaleido 3, since better sharpness just meant you got an HD view of the colour filter.
