Acer Switch 10 annoying Gamma shifts

Hi,

Is there a way to stop the device from "optimizing" the Gamma value in respect to what the display is showing? I already tried disabling Lumi Flex in Acer Quicke Acces (therefore uninstalling and trying different versions of the quick access panel). So i thought it might be something that by accident was coded into the bios and therefore did a bios update, but it did not work either.

Resetting the device to factory default also does not work. So my last resort would be to install a non OEM Windows without any bloatware that might cause this problem. Is there an easier way to fix this?

I use my switch 10 primarily for studies but also to show some images to people and this function makes images (in particular skin tones) that were edited on a calibrated screen look bad, really bad.
