PG35VQ Wrong factory calibration , is there a way to remove?

[Leonidas44]

Hello guys , as the title says i received my PG35VQ with a very bad factory calibration , my monitor has a green pale tint which ruins the picture quality. I calibrated further the display using my xrite colormunky to remove that green tint , get the colors right and get that gamma to actual 2.2.... But while this works great for sdr it introduces banding in hdr.

Is there any way to get rid of this unacceptable factory calibration???

I already tried a factory reset but these settings seems to be somewhat saved within the monitor.
