OK, try out <http://www.argyllcms.com/dispcal_win.zip>, and set the (new) -A parameter to some value between 8.0 (the default) and 1.0. e.g. try 4 to start, or even 2, and see if it changes the coloration near black. Note that a value of 1 will create a linear blend between the white point hue and the black point hue. Graeme Gill.
Okay, just a quick update: the new -A option reduces the visual differences between the low neutral RGB values. I used your recommended starting point of setting it to 4. Compared to without the blending, differences minimized noticeably. I will have to experiment with that more tomorrow. I was only able to create quick profiles with dispcal as of now and thus had no opportunity to use profcheck (no .ti3 reference without dispread). Thanks for your effort, I will let you know what further testing will show.
