>>4303417Visible grain doesn't mean all the detail is captured. Unlike pixels, grains have size and shape that take more than one pixel to be measured.
Look, here is the pixel-shift and non-pixel-shift images scaled 1/4 to match the non-pixel-shift bayer groups. The pixel shift is clearly sharper and has more detail. So the non-pixel-shift was not capturing all the information. Without an even higher resolution to do the same comparison, I don't think we can say whether the pixel-shift is capturing all the details or not.
