If I apply a luminosity mask to an image by selecting a RGB channel(from a layer that has been desatuarated via luminosity) with any of red, green or blue channels as the mask, if I then go on to adjust by curves (*value*) I get a shift in colour, as you would expect if you where using red,green or blue separately in curves not by value. Alternatively if I create a new layer desaturated to luminosity as you would before, but then drag that *layer* to the channel dialog box,then apply that new channel as a layer mask, I get the expected adjustment using curves(value) that it does not shift the colour. Also if I apply a mask from a RGB channel, then remove that mask and layer, also delete the dragged channel, add a new layer I cannot desaturate that new layer as it maintains colour. If I do the same with the original layer (opened image) you can desaturate that original layer.
