When talking about the extent of a color gamut, all that's really talking about is the most highly saturated bright colours it can portray, which is only one small aspect of colour accuracy. It says nothing, for example, about the monitor's accuracy in displaying whites and greys, its accuracy in gamma and its ability to portray skin tones, and other mild ...


I attempted to duplicate what you are describing. I created an image consisting of the color you specified. I had to guess at how much saturation you were adding in the adjustment. In Lightroom (Develop>Basic>Color>Presence>Saturation) I added 100 saturation. (I'm not sure what steps you were going through, but if you specify, this may help get a clearer ...


LCD monitors are "linear", and do not need gamma today, but CRT monitors are nonlinear, and still do. And all the worlds archives of existing images do have gamma for CRT, so it's much easier to continue adding gamma than to change all software, and obsolete all existing images. The human eye absolutely has no use for gamma. The eye sees the original ...


What is a percentage of sRGB anyway? These numbers are pure specsmanship. Most look percentage of area covered in either CIE x,y or CIE u'v' ... whichever gives the bigger number. The real way to compare gamuts is using total volume in a perceptually uniform space such as CIELAB. The author of this answer is correct that none of these gamut comparison ...


Just to answer your question: If you have that single image that has most of it's shades in the area where the two monitors color space differs, you'd probably are able to spot a difference if you compare them directly. Unless you have these two monitors standing next to each other, you'll most certainly never notice any difference. Don't emphasize ...


The OP is pretty much all correct, except that gamma makes the dark tones brighter, not dimmer. This exists just in the file, not in the eye. The data is always decoded back to original linear BEFORE any eye sees it. Any difference in the eye seeing the original scene, and seeing the reproduced decoded data, is simply an undesired reproduction error. ...
