Been testing my new camera and noticed a dead pixel

Searching the web it seems like it's quite a common occurrence and people are advising just to photoshop any out?
Very easy to photoshop it out, but should I? People are implying I could try 10 different cameras and all would either have one or two to start with, or develop them over a year or two and that Canon will simply run a program that merges it (or something like that) with the next pixel if it's repaired?
Ignoring the photo content (was just testing the camera), the first pic is it's original where you cant even see it. The white box is the bit I've gradually zoomed in on on the other pics.
