There is an old LCD the monitor which peeps. At brightness setting in 85 % and more peep disappears. Operation behind the monitor at the installed brightness in 85 %  for eyes.
There was an idea to try to change parameters of color profile RGB - to lower all three parameters RGB on one value . By default parameters RGB - 100 %, at lowering of all three parameters RGB on the same value (for example, to 80 %) the picture becomes more dark.
Questions:
1. Whether such change of color profile RGB influences image brightness of the monitor?
2. Whether such change of color profile RGB influences picture contrast of the monitor?
3. How much such method generally is applicable in respect of influence of a luminous flow from the monitor on eyes? Whether will be worse, than at brightness in 85 % and all three parameters RGB in 100 %?
Search gave nothing on these questions.

Yes
Whether such change of color profile RGB Influences picture contrast of the monitor?
Yes, it is possible to reduce visibility simply.

All individually, someone from  escapes unscrewing on  brightness and reduces contrast, on the contrary such picture seems to me "poisonous" and tires eyes.
