You need to set yourself some numerical targets. Like 90 to 100 cd/m2 for the white and 0.30 to 1.00 cd/m2 for the black.
The target values for black are the 1% values.
On a related note, if I repeat the black level portion of dispcal it wants me to go lower with each iteration despite meeting it's target each time. Is this just trying to get to a level of 0 limited by the default -k factor? Is there a level I should be aiming for short of pure black?
I'm not sure about this, as I haven't observer it myself. I would expect some interaction between brightness and contrast (offset and gain) controls. Does the black level vary much ? Is the change getting less each time around ? The pragmatic thing is simply to stop after one or two iterations, probably after the black adjustment, since it is likely to be more critical.
