@canofhumdingers: That is a good point. I think that we are most of the way there, because we are disputing the smallest changes in hues and tints! At least the "blue filter" of the official release is gone.
That said, it would be a shame to get almost there and give up because it is too difficult.
Also, to put it out there, my monitor is not calibrated, but is mostly correct (lines up with what others are seeing).
