I am not "assuming" -- I am defining "equally efficient sensors" as two sensors with the same QE, same read noise / area, and same saturation limit / area.

If these were ideal sensors, you would have identical SNR and DR for the same output size.

However, in practice, no two sensors with these characteristics can be made on the same CMOS process. Thus, by definition , you are comparing apples vs oranges - if these were real sensors, not ideal ones.

Exactly!
