it just a plain colour calibration on the monitor, to make sure that the colour shown on monitor as accurate as possible. usually people achieve this by reduce colour intensity abit.

for people that didnt do colour critical work, no need to bother much. as for me i like my image as vibrant as possible without any colour value change, so i just leave to what native gamut that the screen can provide, except if the image looks very warm, then i will reduce the red colour intensity abit.
usually monitor that was made for srgb gamut hardly look warm
