I requestall m53 user to pleasesend a email to the ceo if you are facing bad display experience at low brightness (in dark room)in samsung galaxy m53 and others too they are just ignoring the problemhttps://contactus.samsung.com/customer/contactus...

There is temporary solution bro try if it works for you in dark room adjust brightness level to high and turn on extra dim mode black gets better in my case @Shivang1983 (after your dm did some experiment)
