My LG OLED had intermittent contrast issues that persisted after toggling every permutation of picture bell and whistle. After finally stumbling across the correct search term, it turned out the offending feature was hidden in a maintenance menu that requires a button that only exists on service remotes… The same issue was fixed in an update for newer models. Tons of forum posts on the subject resulted in RMAs and refunds. How did we get like this?
