Seeing others say their OLED decks, more commonly the LE ones, have a dead pixel made me check my LE deck for one and sure enough I got a dead pixel. If I never checked I probably never would notice it in regular gameplay. Now all I do is fixate on that dead pixel now. I’m really contemplating whether this warrants setting up an RMA when everything else is fine with the deck.
What others have said and sadly pixels can die after it leaves quality control if the machine is subject to bumps and trauma.
