Disparities between recording application and recording screen

[HappyTrigger42]

Hello, I am battling to figure out why is OBS ( version 28.1.2 ) giving me a dark overlay when attempting to record my screen and not when recording the application directly ( without editing any settings / not using any filters )
Here is a screenshot of the game itself :

And here is the exact same view but using the screen capture rather than the game capture :

As you can see the second one is darker and not having realised the issue, I need to redo some footage
Here are my video settings just in case, they are the same for both scenes :

To be honest I am very unsure of what the settings do
What confuses me a lot is that it's the same settings for both and there is no filters. So why am I getting this dark overlay on the display capture ?
Changing the display capture method yielded no visible differences

( I used the windows 10 capture for the screenshot )

Any help would be much appreciated

I had a similar problem and only in Assassin's Creed Odyssey. The solution was to disable the use of full screen display in the game.

Well, in my case the game is the only one working :/

Ok so I found the issue
Turns out windows enabled the HDR option on the screen
This ended up over exposing the screen recording for OBS
I found the solution after using keywords such as "underexposed" and "overexposed"
Here is where you find it :

I'm very unsure of what exactly it is supposed to do ( better colours ? ) but obs and a few other recording / screen sharing softwares do not like it at all
