Hey guys, i recently got this 4k SUHD LG tv. it is the model SJ850v (also known as SJ8500). overall it is a very good tv, especially for my gaming needs with low input lag on Game mode. but the gray uniformity could be better. (has mild clouding on black screens.) but what really bothers me the most now is, while i was cleaning it abit with a microfibrecloth, i noticed this tiny 1 dot stuck pixel. it is multi colored (RGB) and i am afraid that this could spread and i would want to avoid that. is there a chance of it spreading ? (note : i had my n3ds xl since over 2 years now and it came with a stuck pixel and it did not spread, but tvs are different so i wanted to make sure.) because the tv is not cheap, paid 1000$ for it. so if it is not safe to keep it , i will go and replace it.
