When I just calibrated with: dispcal -v -d1 -c1 -P0.5,0.5,1.0 -H -qh
-w0.312713,0.329016 -g2.222222 -f1 -k0 -A20 -B0.01

I got a warning message at the end: dispcal: Warning - Black brigtness
ignored because it is out of range

That will happen if the -B parameter is less than the actual measured
black point. -B is for artificially increasing the black point to simulate
lower contrast media.
