but apart from a little better sharpness -which is questionable-, color is not improved by pixel density and noise in generally worse. First you said color was not improved, now it's useless because of 4:2:0 following hmcindie. Noise will not be worse but better, reason? Blue channel noise, the more pixels you have, the less purple crap will be prominent from the blue pixels. Color is better because you are sampling colors more often, this will give a better image, the 4:2:0 losses will make it worse, but that also happes to the not oversampled image, so it will still be better. Sharpness will be also better, just compare a 12mp file to a downsized 36mp, it's obvious. But hey, come up with what you want, I don't get a price or anything for doing this.
