If you understood what DR was, then you'd not be confused on this point. Would you like me to explain to you how it works out? Specifically, why neither sensor size nor pixel size figures into the calculation of DR?

Maybe you should explain it to Chuck Westfall, Technical Advisor in Canon USA's Pro Engineering and Solutions Division. who says

'There's a couple of things that we consider when we think about IQ: number one on this sensor is noise. It's clear the noise level is better than in the 1D Mk IV or the 1DS III. The pixel size is larger than in the 1DS III or 5D Mark II (6.95 microns, versus 6.4) and the difference is even more striking compared to the 5.7 micron pixels in the 1D Mark IV. That helps us in terms of light capturing ability and increases the signal to noise ratio. In turn, that does nothing but help the dynamic range of the camera. '
