Yeah, I know it's possible and that it'll reduce the magnitude of the ICC profile adjustments; the question (although I feel it's not all that super relevant) is whether the net result is any different from calibrating the whole thing in software space to begin with. I'm hesitant to accept there's much of a difference because in the end, AFAIK the only way to make greyscales on a pixel (=color for RGB pixels) is to modulate the pixel between on/off rapidly as they don't have a semi-transparent state by definition (the pixels are binary). The modulation bandwidth is ultimately hardware limited and not adjustable within the hardware implementation. That's why I put 'hardware' calibration between quotes because a more apt characterization would be 'firmware' calibration that adjusts a LUT within the monitor's software, but it'll still by necessity have to work within the same total modulation bandwidth.
