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.

Using more of the non linear part of the photon transfer curve? That may make some sense on a monochrome device.
