This is done somewhat differently on all screens, so you will have to do some experimentation on your own to fully figure it out.
That said, if you look at the CIE Diagram, it will help you understand these comments better. The dark triangle is the rec709 target space. The white triangle is the actual measurements.
Many screen have more color error at 100% intensity than at 75%, and since most colors are actually at 75% or less, for the sake of calibration, you should use the 75% Color patterns from AVS709 for calibration purposes. Make sure to let it calibrate a 75% grey as 'white' as well to give you accurate Delta E measurements.
The "Color" or "Saturation" setting in the main settings area for your screen will by a blunt tool which will make the triangle somewhat larger or smaller for all colors at the same time as you adjust it. You might get somewhat more accurate Delta E's by lowering the Saturation in the main control a few clicks. Picture modes also have some impact on color rendering on some screen, "Calibrated Dark" will likely be the most accurate for colors. If there is an adjustment where you can force it to rec709, that will also perhaps have a big impact into bringing it in line.
Once the "blunt force" tools have been tweaked as much as they can be, it's time to move into the "CMS" (Color Management System) settings.
Hue will affect the left-right rotation of that color on the triangle, so the Hue setting for Green will move it more towards yellow or cyan. You want to move this closer to yellow in this case. Saturation controls the distance from the grey point, so likely some points are oversaturated while others are probably closer to the correct saturation -- Green and Magenta are probably the most oversaturated currently. Luminance controls how bright the color is (same color, more or less light allowed through). You can look at the Delta Luminance measurement as you adjust this. Currently, they look pretty close. Human eyes are much more sensitive on Delta E than Delta Luminance for colors.
I would suggest doing one color at a time, starting with the primaries, in order of most error to least, (So, green, blue, red), and adjusting Hue, then Saturation, then Luminance in that order for each color. Once you have those adjusted, you will then move on to the secondary colors (Cyan, Magenta, Yellow). You will likely have to do two passes, as each color you adjust will have an impact on the other colors as well.
