I went to the store and showed him the picture. In fact, there was 2 guys. One of them just said "Megaman, hahaha... awsome".
They asked me to bring back the tv and exchange it for a new one right away. Great service, really satisfied.
The new one is super black on all corners. Yay !!!
ps. It's pretty cool that I picked that opened box, got a discount on it, and then exchange it for brand new one
