In regard to not being able to control the monitor's parameters on Windows due to the lacking OSD, have you tried using any DDC/CI software (such as ClickMonitorDDC) to control it? It seems that DDC is a standard developed by VESA (https://en.wikipedia.org/wiki/Display_Data_Channel) for the purpose of controlling monitors through software.
I control my monitors like this and I can adjust the varies colour profiles supported amongst other settings that are usually cumbersome to adjust through the OSD compared to using ClickMonitorDDC (which is what I use but there are others).
