He has never been stated, hinted, or even implied to have it. He was always known for having the Rinnegan and that's it. The Rinnegan even existed before the Sharingan did. So I don't see why he should have it just because he has a Rinnegan. Rinnegans are not upgraded Sharingans, Sharingans come from Rinnegans. Sharingan is essentially a weaker and devolved version of Rinnegan.
