The saturation (or to be more accurate in this case, chroma) is actually already as high as possible (unless I’ve made a fundamental mistake) given the constraint that we want it to be uniform across colours and also uniform luminance. sRGB simply doesn’t allow for more sadly and I’m afraid it will probably be a long time before a new standard colour space for consumer displays comes around that would improve this.

This tool that others have linked is pretty good if you’re fine with relaxing the constraints (just make sure to change to colour space to LCH OKlab): https://huetone.ardov.me.
