Purchased a 75" TV, UN75MU800D, Serial #06A3CBJA00388R almost 3 years ago. I now have the dreaded "banding". I have been a strong Samsung customer. The operative words are "have been". Own two Samsung phones and several Samsung TV's, the 75" being the most expensive Samsung item I have.
To say I am disappointed, especially how many others have this problem, is a total understatement. Will have now consider other manufacturers for future purchases.
