Hi, I just got a new LG C8 65in. I ran a pixel test and noticed a single white pixel on the red screen. I also noticed one more on a blue screen (different sub pixel). Is this normal or is it worth it to exchange the TV? I ran the pixel refresh which didn't do anything. Now I'm running one of those repair videos on youtube to see what it does. If this is a rare issue then I will definitely go exchange it but if the probably of this issue is pretty high, then I may get one that is the same or worse when I exchange. Thoughts?
