>>4422876ccd was thought to have "pop" because early on consumer CCDs counted photons more accurately than CMOS. this is also the color magic, just each R/G/B site outputting something closer to what went in.
big pixels, likewise, made up for deficiencies in earlier sensors (FSI, gapped microlenses).
today le big pixel CCD is not actually doing anything different from a pedestrian camera like a nikon z6ii other than having a pixel pitch larger than some lens aberrations maybe. the gear is not really magic. cameras count photons like keyboards count keystrokes. they are basic tools.
