Switching to power saver changes the contrast of my screen (propably to save power) but it doesnt revert back to normal when switching back to balanced or performance mode.
I’m aware that night light is enabled and I know it makes the screen warmer and I don’t think the contrast is very noticeable in the picture. I’ll try capturing more pictures if needed. The only solution I’ve found so far is to either switch to balanced mode and restart my laptop or log out.
Do you want to disable the contrast change(panel power saving)?

I know how to disable this I am asking if there is a way to make it work as intended (switching back to balanced mode should make the contrast back to normal)
Seems like a bug. Report it here Making sure you're not a bot!
But how did you enabled it tho? I can’t see such settings (GNOME 49)

enabled what exactly?
High contrast on power saver
I didnt enable it. Contrast changes by default for me when i turn power saver on.
I see, I misread your post, sorry!
So, first of all, I see you use extensions. Can you disable them and see if the problem persists? If yes, then you report the bug in the above-mentioned link. If no, then try to find out which extension is causing this and report it in its repository.
No extension is causing this behavior.
If you override the panel_power_savings from tuned does it change anything?
Assuing you don’t have any overrides defined already, if you do you’d need to add this to the file.
sudo mkdir -p /etc/tuned/profiles/overrides
sudo tee /etc/tuned/profiles/overrides/tuned.conf << EOF > /dev/null
[video]
panel_power_savings=0

Being a newbie and not very tech-savvy, all I can add to this discussion (using Fedora 42/KDE on a Dell XPS 13) is that I am experiencing a similar, not exactly the same, issue: when my power drops to below 15%, my screen‘s brightness automatically drops. Previously, on Windows, it would go back up when I plugged a charger to my laptop.
While I can confirm that the power mode goes back to BALANCED when I plug it in, the screen‘s brightness does not go back up.
To be clear: I personally am not too bothered by this, I am just trying to give another perspective to the issue at stake. I do not know if this contributes to the larger picture, but I hope it does!

OP’s issue is that contrast settings change, not brightness. Your case is actually expected and isn’t a bug.

Will try this once i get back home.
ok so i have tried this but what does it do? does it stop the contrast changing?
hi! i have had the same issue for multiple months now, but didn’t know that was a bug. the contrast requires going into sleep mode, hibernation or powering off to get updated on amd gpus
AMD cards have a power saving function that reduces power consumption by reducing color accuracy. Setting it to 0 disables it.
@omegasomeone Making sure you're not a bot! I believe is what you’re talking about, also Panel power savings not activating until suspend/resume (ThinkPad T14s Gen 4 AMD, Fedora 42) - #2 by mulkinh
ok i get it but i dont want to disable color accuracy on power saver on 20% i want to it to switch the color accuracy back to normal like when i am not 20% or below or i switch to balanced or perfromance mode
Setting it to 0 should disable the panel_power_saving changes for all the profiles (powersave, balanced, performance)
It looks like it’s only set during the powersave profile.
Thanks for the response, but I was actually asking if there’s a known fix or workaround to revert the high contrast mode once it’s triggered by switching to power saver.
