No! You'll never get the black out of a diesel engine! I've flushed my 2006 Fiesta 1.4Tdci three times with cheap oil (six quid for five litres from Morrisons petrol stations), and each time it comes out black! But change the filter yourself, or at least check it after a service. When mine came out of warranty, I did an oil and filter change, and from the condition of the filter, I don't believe it had ever been changed by the dealer! Perhaps they'd never changed the oil neither, but you just can't tell - it will always be black. That's a diesel for you.
