Is dit niet een Carolina x Wilde eend?

bluegrey bill with pinkish color on upper mandible and violett head gloss, very dark back and light flanks-- I go for tufted duck x wood duck, kuif x carolina.
the whitish iris is odd but this is the 3rd bird I see that looks like Kuif x carolina and has a whitish iris.
I have no idea what else this could be.
Wilde x carolina should have green head, brownish back, mainly yellow bill
thinking of the kuif x witoog in the other topic, could carolina x witoogeend be a possiblity for this bird? Although maybe unlikely...
