I have not measured, is their a tool to do this within the Optix software?

After the first cal/profile, create a ramp 0 to 255 RGB in PS, view in
monitor RGB, and posterize to say 64 levels. Note where the bands are not
neutral as an RGB value.
Then in the Grey Balance tool within BasICColor Display add extra grey
calibration steps to match the non RGB value neutral areas, save and
re-profile. This then helps with the non-linear nature of LCD screens and
shows the improved delta e.

The assessment was on this monitor in relation to the previous profiles and
my 'memory' of the Artisan.
