It shouldn't have worse gray uniformity/edge bleeding. The screens are all made after the same specs and probably in the same factory by the same machines. I think it's worth getting it replaced as soon as possible, if you're anything like me that stuck pixel is going to bother you to no end. 30 mins isn't going to fix it, I really recommend you leave it for 24 hours. Do it when you're away from home for a day. But for now at least run it overnight and see if that helps. There's probably another 3.5mm jack for the white and red, so you'll need a 3.5mm to 2xRCA adapter if one didn't come with the TV.
