I agree to an extent, Luffy saved the land like Ryuuma hence he's now renowned across Wano due to it but Zoro's Ryuuma parallels still exist.
They're both one-eyed samurai and it was highlighted by Kawamatsu in the middle of his arc fight, plus he slayed King's strongest attack that took the form of a Dragon, similar to Ryuuma slaying a dragon and being famous for it. We'll see how far Zoro goes but I wouldn't be surprised if he surpasses the Sword God and it's highlighted.
