I haven't been able to post until now, but I also got the exact same model/color/serial from walmart and it had 4.5 on it, so I can confirm the blue 1270.
Long story follows:
I got it on Thursday night with a price match for 149.99 at walmart as I didn't want to wait in the lines and crap...
I've been playing fallout4 all day, I went into a elevator and it kept going, never stopped, waited 5 minutes, must of been a bug. How bout you, whatcha do today?
