I currently spend all my time in 20H2 now on my HD 6000. My recommended update procedure for any version of the OS on a clean install with the network not connected, separately download the SSU update and install that first (especially if you're using something ancient like 1507!). Then install the cumulative update from the windows update catalog. This way it won't be a script getting confused as to what to install in which order. You just need a 40 GB free space partition to play around, it won't screw up your other OS install if you do custom install and select the new partition.
In addition, in the classic control panel for color management, once your monitor is populated in device manager with a profile instead of generic pnp, two additional boxes need to be checked.. on the first tab "Use my settings for this device" then on the advanced tab click on change system defaults click on the advanced tab there and check on "Use windows display calibration".
In Intel driver settings, my monitor is currently connected through a displayport to hdmi adapter and in the settings I have "full range" under qualitative, it content "off" and in color settings I have YCbCr set (this is running in 4:4:4 mode for me, not 4:2:x).
Be careful what sharpness level you have the display set to.. you want to avoid white ringing around black or black ringing around white. Use a calibration pattern. On my monitor I was using 40 for a long time which is sharper than 50, but I've recently determined I was experiencing more ringing/haloing around letters than with 50 and this was more visible because I don't use anti-aliasing around text. Optimal setting depends on the display being used.
Use the Inspectre tool to turn off spectre and meltdown protection to regain some system responsiveness especially if you have an older CPU.
