iPhone 12 pro max Dim Glow present even after ios 14.5

i am experiencing dim glow at minimum brightness or at certain conditions like watching youtube videos and while seeking videos seeing a glow near the notch. or while viewing a photo in gallery above and below of the photo seeing a dim glow. mostly dim glow is seen in the photos app. is anyone experiencing the grey glow/dim glow even after ios 14.5? what do you think because at this point i think its a hardware issue its been 7 months till now apple couldn't fix it and not all iPhones 12 has it so i think its hardware related to some iphones
