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

The QHY600 monochrome astro camera, which uses a monochrome IMX455, has a full well capacity of >51,000 e- > 3,607 e-/um^2. (51/37 x 2617).

I assume the advantage lies in the lack of a CFA.

I don’t see how removing the CFA would affect the FWC. Maybe that camera uses a different nonlinearity threshold.
