Just as a note: If the anime shows something that the manga did not show, it does contradict the canon. The argument that "it's not shown in the manga, but he might still have it" isn't valid, because going by that, anyone can have everything, "it just wasn't shown". Basically, there are three levels: Said not to have X - No word of having/not having X - Having X. Each level contradicts one or both of the other two. So if Hagoromo is shown having a Sharingan in the anime, but there's no mention of it in the manga, then the third level (Having X) contradicts the second (No mention of X), not the first.
