Instead of a LUT altering the display behavior (calibration), the panel is doing this while PS/LR still uses the ICC display profile to 'know' about this condition to produce previews. Basically, nothing is different from the last process as far as you are concerned, but there's greater precision in the calibration taking place in the hardware vs. using software from the LUT. And you're using a MUCH better instrument (the Spyders are not so great). There is nothing more you have to do once you calibrate at the desired (which is ideal) calibration aim-points.
