Depends on when you checked the oil level and whether it was on a really level surface when you checked it. If it was on a level surface but the engine was recently switched off (ie checked level within 60 seconds of switching off) then it may be even more over-filled if you wait a few more minutes to let all the oil drain down.
My dealership has slightly over-filled mine (5 cyl TDI transporter) at the last two oil changes, but only to about 2-3mm up from the bottom surface of the top bulb with the engine oil completely drained down.
Your dealer may be trying to "help" in case your engine burns a bit of oil (some new TDI engines do go through a bit of oil at first).
If you want an indication of how confident they are about the level they have filled it to you could ask for a letter signed by the service manager (or workshop foreman) describing the exact oil level and stating that this will not harm your catalysts (or anything else), and that they will cover these in the event they are shown to be damaged by excess oil.
If they are reluctant to supply such a letter then I'd be insisting that they remove the excess oil. Often when people are unwilling to put down on paper (and sign) what they are telling you verbally it indicates you can't rely on what they are saying.
