Thanks for the follow up Noris. I really appreciate it. I apologize for the delay in getting this to you. I was having a hard time working with the touch screen on the windows tablet to get the information.
The graphics driver just shows as Intel HD Graphics, which I understand is somewhat of a generic driver. I think it is customized from Dell as part of the Venue 8 Pro tablet chipset. There is no dedicated graphics driver available.
The below link is a ZIP file with the Roon logs, details about the machine hardware, as well as screenshots of both the light and dark themes. In person, on the actual tablet, the screen images are even a bit brighter. I used a docking station and external monitor to capture everything so that may have somewhat reduced the intensity, but it is still way too bright. Either way, it is much brighter and more washed out than the rest of the general windows theme on the tablet.
