Oh, sorry. I didn't try your test build because somebody took that laptop
with her for a couple of weeks.

But otherwise what about a calibration mode like this:
The calibration starts by measuring 3x256 (256xR,G,B) patches to identify
the usable device value ranges and make the first iteration of the
calibration curves.
A few points are measured with that LUT to plan the next measurement set
(very low error -> finished , low errors -> use a few more sample for a new
iteration , very high errors -> use a lot of patches for the next
