Full well capacity per unit area has maxxed out at around 3000 electrons per square micrometer (3000 e-/um^2).

So if I understand right , the Z7 sensor tech at MF size would yield higher PDR than GFX at base iso ?

No,

You can deduce that the Z7 has higher SNR at the pixel level.

For PDR, you need to take the readout noise and the pixel count into account. The Z7 has larger pixels which means fewer pixels for any given size.

Hmm, I thought the rightmost column values are normalised to unit area (hence pixel size independent)
