[argyllcms] Delta-E - the wrong value to optimize?

I have a plasma monitor that looks much worse when calibrated - bad posterization in the brighter reds. Is there anything I can do? Perhaps DeltaE isn't the right function to minimize and a new function that corresponds better to how a human will perceive the overall look is needed - ie, smoothness is critical. Any suggestions on modifying the code (feasibility, where to start, etc)? Any tips on why this is occurring? Is 8 bits/color just not enough?
