Aren't specialised "low-light" cameras lower in pixel-count because fewer pixels implies lower read noise from the electronics?

No.  Typically low-light cameras have larger pixels in order to gather more light (more photoelectrons per exposure). For a given set of optics or sensor chip area, this typically means fewer pixels.

Here is an example of a 16Mpix sensor with 1.1um pixel pitch and also the lowest reported read noise (0.19e- rms average).  Also a great performer in low light.
