http://www.darktable.org/usermanual/ch03s04s02.html.php Well, your assumption is wrong. tone curve works in Lab all the time. And in manual mode, it will do exactly what you expect. If "scale chroma" is enabled, it will increase the color contrast as well, to match your visual experience closer. This sometimes fails for me, especially for red tones, but there is a blend mode to reduce the strength of the effect.
