Speak with the dealership manager, have the complaint on the record, and ask for some comps. Too much oil in the crankcase can foam the oil, causing minor wear due to air bubbles in the oil. The oil is supposed to be checked on a cold engine.
.1 L is nothing, .5 L is something, and 1 L is way too much. If you think about it, that extra .5 L is spread out over the area of the oil pan so it's only a little higher and shouldn't have caused too much damage from extra air bubbles in 1 day. How much higher on the dipstick was the oil level than the has marks?
If you complain loud enough, maybe they'll give you an extra year warranty on the engine or something but that would probably be at the dealership end and I doubt your engine will blow up. They'll just drain the oil a little or suck it out the dipstick.
