I set vibranceGUI to 50% windows level, 80% CSGO, and autorun on windows launch + affect only primary monitor. It worked well in-game, and it did not affect my secondary monitor as expected, but when quitting CSGO, my primary monitor's contrast and brightness were messed up. It looked like a transparent gray filter was applied to it. I have attached working/non-working fixes, hardware and expected/actual screenshots of the issue below.
Fixes I tried that did not work:
Exiting vibranceGUI through task manager would not work, the color profile was still messed up.
Installed new NVIDIA drivers would temporarily fix the issue while installing, the color profile would return to normal, but then after a few screen flashes to black it would return to the incorrect color.
Removed drivers through DDU, similar to re-installing NVIDIA drivers, would work during the install, but after the PC restarted the color/brightness were still messed up.
Adding a new program to vibranceGUI (discord.exe in my case), and alt-tabbing to it would just change the vibrance, but the contrast/brightness were still incorrect.
Launching CSGO again and exiting did not work.
Disabling "autorun" and "affect primary monitor only", removing vibranceGUI from startup in task manager, deleting the data from AppData/Roaming/vibranceGUI, using DDU to reset the drivers. Issue goes away during driver removal and when starting Windows with only one monitor connected, when the 2nd monitor is connected the issue comes back.
Workaround that fixes this (but the colors still look a bit worse since its YCbCr422):
Setting "Output color format" to "YCbCr422" in NVIDIA Control Panel => Change resolution => 3. Apply the following settings => Use NVIDIA color settings => Output color format => YCbCr422. If this is set to YCbCr444 or RGB the issue persists.

PC/display specs:
primary monitor: 2160x1440@170hz secondary: 1920x1080@144hz GPU: GTX 3070ti, drivers 531.79
No display color changes in NVIDIA or monitor settings were applied before, all settings were set to default at all times
