Windows 10: Windows 11 / Lenovo laptop changing brightness and contrast automatically

I'm on a Windows 11 laptop, Lenovo Yoga Slim 6 14IAP8 - Type 82WUI've been having issues with the brightness and contrast changing automatically, even though I've changed multiple settings which should've turned this function off. This is important, as I work with programs where color accuracy is a priority.Here's what I've tried:Turned off these 2 settingsChanged my power plan to performance instead of balancedTurned off the option to auto-change brightness in Intel Graphics Command CenterChecked BIOS settings, but there was no option to turn this offThis has been a real pain, if anyone knows

Screen contrast changes depending on brightness.

I am using Windows 11 Pro build 22631 on dark mode and there seem to be some kind of adaptive brightness/contrast that changes if the window I'm in is dark or bright (usually more noticeable when browsing the web). I searched for a way to disable it but couldn't figure it out. The information I found online points to menus that don't exist in my version of Windows 11 (like "change brightness automatically when lighting changes"). Anyone knows how to disable this so my colors/brightness/contrast doesn't change?

 

Changing contrast and brightness for a laptop

I have bought an acer nitro v15 for my brother and its a good device but most importantly the screen looked amazing, so we bought another one but the contrast is extremely low, and there is no way I could find for a way to change the contrast and brightness from the OS, in the color calibrations it just says to press the buttons on the display, but laptop screens don't come with buttons for that. The high contrast feature is useless for us because it changes everything to weird colors and I rely on colors for my work a lot I need a normal higher contrast.
