71 Plate Aygo front bumper very slightly misaligned

[Ixon1976]

I bought a 71 plate Aygo with under 11k on the clock just over 4 weeks ago from a Toyota Dealer, I've only recently noticed that the front bumper is ever so slightly misaligned, what gives it away is where bumper meets the wheel arch driver side is flush, yet the passenger side has a slightly bigger gap we taking millimetres but it's noticeable. 

Do you think this is a none issue & me being OCD about it, or is it worth taking back to the dealers to have this sorted?.

One of those things where once you've seen it, you'll always notice it. Pop it back to them and see what they say.
