Soooooo... I went to the depot and was able to collect my phone

So who cares about the missed delivery - it's here! And it's gorgeous!
HOWEVER
It has one dead pixel
The question is, what should I do now:
1. Return this phone and wait for weeks for a replacement
2. Live with a dead pixel for a while and then replace it when the stock will pick-up.
3. Just learn to live with a single dead pixel.
What do you think?
Is it likely that more pixels will die if one is dead already?
P.S. The pixel is in the top right corner, next to a battery level indicator. It's hard to see on non-white backgrounds.
