Which is either cosmetic or even counterproductive (if the RAW is bit-limited). If you multiply the ADC output digitally and write that to the RAW file, you gain nothing. If the RAW file is limited to 12 bit, you may even lose dynamic range that the sensor/ADC has otherwise captured perfectly.

You lose only DR if the sensor actually records useful data in the low-order-bits and not just noise. But in higher ISOs the low-order-bits only contain more or less random data and it doesn´t matter if you have just noise or clip them to 0 (which happens when you multiply them)
