Here is a telling paragraph, written by the achromat's extremely detailed
biography
as Jeremy notes above:

"Coloured and B & W pictures are usually indistinguishable to me. But
sometimes I can, often quite easily, tell coloured and noncoloured pictures
apart. Coloured pictures may look less crisp, or slightly less in focus, and
often have less contrast than comparable monochrom pictures."

Proof that images originally in color suffer from lack of contrast when
desaturated.

((Another line from the biography:
"I have one sister (born 8.10.1943) and one brother (born 5.10.1945) who are
both, like myself, typical, complete achromats, confirmed by the
anomaloscope."
How many anomalies the anomaloscope can check today might be an interesting
question.))
