I visited service center they denied it and contacted Samsung shop support they denied it, I sent these proof photos to twitter comment support guys still he denied it saying there is no issue with your screen. Worst experience from Samsung. I've been using flagships lineup from S7edge so I'm big fan. But I'm regretting my decision regarding this phone-S24U. So My humble request is to new buyer don't buy it yet just wait until till this issue get resolved because very few people have display without this defect or issue (or Samsung might say it's a new feature). Samsung have addressed the color issue and said update will fix it, but they are not accepting that this grainy display issue is defective or problem. So I'm pretty annoyed with how they're dealing this issue. If you wanna see grain then in night time in dark room enable the extra dim mode and lower down your brightness open any app and other then pitch black color on every other color you can see grains (jeans type pattern). So please comment and like this post so this post can be heard to higher level.
