I think you're right..

That reminds me, take a look at this bird that I photographed in Lincolnshire (UK) over the weekend:

Presumably Red-crested X Common Pochard?

On the A. nyroca x Netta rufina you see a greyish beak with black nail, a fluffed up struckture of head feathers and a paler more greyish area with some vermiculated feathers at the shoulder- all indications of Netta rufina parentage.

Thanks Joern for the help and also for the tip on identification of this hybrid.

Also thanks to Josh for completing this with that female hybrid.

Another Aythya nyroca x Netta rufina for comparison:

here you see the beak has a slightly more reddish tinge than in yours - hybrids are more variable than pure species...

and Aythya nyroca x ferina for comparison:
