I feel that the brightness of gray changes more rapidly between gray 4 and gray 7 than other colors, but I don't know how other people feel about it. Do you have any methods to quantify the perceived brightness?
Unlike other colors, gray has functions in the UI design, so the shade steps are not constant. I think this post will explain, somehow why this difference occurs.
