Now I am confused.
Is the LUT included in the ICC profile? If not, how can I make any sensible
comparision between my ICC profile and downloaded ICC profiles if all of
them assume some non-included LUT that does per-channel gain?
Will do a calibrate + profile (with out-of-the-box monitor settings) and
update my table.
regards
