Not really, if you look at the CIE chromaticity diagram, you’ll find that the experience of spectral yellows are very closely approximated by an RGB monitor. It’s spectral cyan that is really out of gamut for a standard display. Take a photo of a green traffic light (which is a little cyan so colorblind people can see it’s not red). I’m pretty sure that green-light color is out of gamut for most displays. https://en.wikipedia.org/wiki/SRGB
