TCL QM8L - Minor Panel Defect at Top of Screen

\*\*\*\*Update\*\*\*\* Best Buy swapped the TV out, no questions asked, and the new unit is much, much better.

\-----------

Hi, just wanted to get some opinions on having Best Buy pick this unit up and replace it for the same model. I'm only asking because I know the panel lottery is real, and I know it can get ugly with large TVs.

Thoughts?
