Exactly. And before the signal is passes into the A/D converter it is filtered from electrical CMOS noise to make it as clean as possible already at that stage. Pure sensor data is not usable and what we regard as raw is indeed processed in some way before

What you are arguing is a symantical argument without merit. You dont purchase a CMOS photovoltatic die, you purchase a sensor. The part number for the sensor includes A/D and on die CMOS noise reduction with I2C output buss. The pure sensor data is the output from that assembly know to the world and the Nikon purchasing agent as the 'Sensor' and its output is prisitine and known as the RAW output void of EXPEED signal processing.
