You anwered this one cuz there is no way you can justify all that crap odas has been doing to sanjis character but I get it do as you like.
In TB ryumas corpse left eye was covered so there was a hint. And zoro has been training and fighting in his own and he is here just cuz of his own mentality and his own power. Like I said sanjis whole power, bounty and the raid suit are all from his family. Zoro has none of that and he did all himself.
But you hate that more than the stuff about sanji?
