U2724DE, Feature Request, Multipoint grayscale adjustments

Hello,
I would love to see Dell implement an option in the monitors OSD to also have a multipoint grayscale adjustments for the RGB channels, for us the coloring nerds.
I have a U2724DE and it's been doing great, but on the other hand I'm also using CalMAN to perform screen calibration services, and when I measure my screen Dell at home, I can make it look "alright" but nowhere near perfect especially if this screen only has a 2 point calibration for the RGB(Gain and Offset) alongside some very basic chroma of only Hue and Saturation.
Well, I did the best as I could, but I can still see errors along the multipoint measurements, for example a big spike from 20 to 40% on the grayscale, and then another spike at 80 to 100% on the grayscale with a DeltaE of >5 which is noticeable.
So my suggestion is for a extra feature via a firmware update to also include the multipoint adjustments in the monitors OSD menus.
Example:
Include a new option in the "Color Presets" menu called "ISF", or "Expert" or something similar(whatever it is) that will actually allow the end user to also have control over each individual picture settings.
