Are people with achromatopsia more sensitive to light?

I know that monochrome cameras are three times more sensitive to light than color cameras, that’s why they’re so useful for astrophotography. Does the same apply for humans who only see in black and white?

In this instance, comparing cameras to human eyes is not an equal comparison. Cameras use the same kind of recording media for color as black and white, either film or some kind of digital sensor. In both cases the difference is thst B&W uses only one layer of film or one sensor, where color has to break the light spectrum into three and either use multiple layers of film or multiple sensors.

The human eye, on the other hand, uses two separate types of cell to evaluate light. One type sees shades of grey, the other sees colors. Missing one type doesn't effect the amount of light the other type takes in.
