Have I been short changed?

I just bought a new bike. Merida Scultura FLX Team-20 frame, with (what I thought was) a complete Dura Ace groupset and other nice components. All purchased via and assembled by my LBS. The bike has a compact 34/50 chain ring and a 12-27 cassette.
I've just noticed that it has a Ultegra chain. Have I been short changed or doesn't it matter, i.e. no difference in weight/performance/compatability?
Thanks,

Ultrega chain is about 2 quid cheaper, weighs the same and is fully compatible so I don't really see any difference. It'll snap in next to no time, so you can buy yourself a new Dura Ace then....
