Malkrazr_shader_srgb -1/1 seem to just make the game extremely dark. By opening the steam overlay I can easily see that the .icc profile has been overridden. Don't quote me on this but I'm guessing that these may refer more to Nvidia color management rather than desktop.
I've added -nogammaramp but I haven't used any .icc profiles nor the switch for nearly 2 years so perhaps it was removed in the meantime. It used to work for majority of source based games though. I've tested dota2, csgo, dear esther, black mesa, portal 1+2, tf2, insurgency and so on.
I'm afraid the only way to force an .icc profile would be to use some sort of an injector but that might trigger VAC so be careful.
