Pale display

Hello, I recently noticed that the colors displayed by my screen are very pale, but when I change the color settings of the desktop in the NVIDIA Control Panel, my image regains colors, no matter what modification I make, even if I revert to the previous settings. Then, if I change the display settings of my screen directly (in the screen menu, not on my PC), the colors remain normal, and if I restart my screen, the colors stay normal (so the problem is probably not related to post-processing done by the screen), but if I restart the PC or display something in full screen, I return to the washed-out colors.
I suppose that when I switch to full screen, another software (Windows display controller?) takes over the display, and when I tweak the NVIDIA settings, it's the NVIDIA driver that takes control. Now, I would like to know if someone has a solution to keep these beautiful colors all the time.
