Wrong colors in-game with Hyperion - how to fix? #2022

Bug report

I'm running a Windows 11 PC for simracing with a home-build Ambilight on the basis of an Arduino Leonardo and 175 LEDs fo W2812B type. I have a 32:9 Ultrawide-screen attached to an RTX3080, a 16:9 1080p screen also attached to the RTX 3080 and a headless monitor dongle attached to the mainboard's HDMI port (i9 10850K CPU)

So far, I've been using Prismatik 64-bit, but I'm planning to move over to Hyperion as I was hoping for lower CPU usage.

While in Prismatik, the colors of the Ambilight are all good, I'm experiencing strange issue with hyperion.

When I run a test video (https://www.youtube.com/watch?v=mNouC8A2mTY&pp=ygUYYW1iaWxpZ2h0IHRlc3QgdWx0cmF3aWRl0gcJCU8LAYcqIYzv), all is good with hyperion.

However, when I run a game, hyperion is having issues with the colors. Take a situation of racing at sunset in Automobilista 2 towards sunglare. Prismatik will grab the sunset at the perimeter of the screen, and make a nice orange-yellow corona around the screen. Hyperion in contrast, somewhat adjust brightness, but the colors stay more or less in the blue range.

What could be triggering this strange behaviour? My gut feeling is that it has something to do with the screen grabbing, but I can't find the solution.

Attached are my settings from Prismatik that I would like to reproduce.
