How to make persistent gamma configuration for the specific monitor using AMD GPU

Hello there! Recently I have bought a new laptop (ZenBook UX325UA_UM325UA) and installed my favorite manjaro distro :). And I have a separate monitor connected to this laptop. Here is the output of the xrandr --query command:

Now, I found out how to configure gamma for the specific monitor like this:

xrandr --current --output eDP --gamma 1.01:0.95:1.10

These are the settings I would love to apply but persistently, for example when I’m on the ssdm’s login screen, after logging into the system, back after hibernation etc. And to do so I tried many things, I went into the different config files like .xinitrc, .bashrc, /usr/share/sddm/scripts/Xsetup (and other its scripts), /etc/sddm.conf.d and more. I even tried to create such config file in the /etc/X11/xorg.conf.d directory:

 Section "Monitor"
    Identifier "eDP"
    Gamma "1.01 0.95 1.10"

But for some reason after applying this config the system does not boot. Perhaps it might be connected with the driver I’m using? Here are some details if needed:

I don’t know what else to try and I need some help. Perhaps there is a better way to calibrate display than tweaking gamma settings? I know there are some ICC profiles and different software (like displaycal), which requires colorimeter, but I am not a photographer so I don’t need it, just to make some simple adjustments to the display and that’s it. I would be very grateful for any help. Let me know if any additional details needed.
