Oliver Sacks wrote that he met someone with achromatopsia who could see constellations of stars better than normal? Is that experience confirmed by others?

Sacks explained his theory to explain this phenomenon in an endnote. He noted that people can sometimes see dim stars better if they look slightly away from the star, because then they are using their rods, rather than their foveal cones. Because people with achromatopsia don't have functioning foveal cones, they don't have these foveal cones competing with the rods. In other words, they always fixate with their rods.
I am wondering if Sacks' observation is shared by others, because I don't see it in the literature (other than his book).
