Update: Dell worked with me to find a solution. The issue was in the Intel Graphics Command Centre power -> System ->Power. The color distortion went away after reducing the energy efficiency settings.  
Hi there. I just bought a new Dell XPS 15 9520 running windows 11. I have this issue where the screen colors look washed out whenever the computer boots up or wakes from sleep on battery. As soon as I open an application the colors automatically restore to what I have set them at in Dell Premium Color and Intel Graphics Command Centre. The issue doesn’t happen when the laptop is plugged in. Does anyone know what might be causing this issue when I am on battery and how I might fix? Many thanks.
