Replacement screen not working properly for dimming below 30%

I finally installed my replacement screen from ifixit yesterday, double checked it worked by turning on the device, before I glued it in place. Unfortunately I did not check the screen functions more thoroughly. When the screen brightness dips below 30% the backlight doesn’t continue it's gradual dimming, but shifts to a dark reddish hue making the screen unreadable at low brightness. Is this a known issue or easy to fix? May it be because of a faulty connection between the screen and the phone or is it a defective screen?

Thank you in advance for any assistance on resolving the issue.
