It would have higher res textures and maybe more real-looking movements and expressions. This would apply to any older CGI model that got updated years later. I’m not sure why the question is about Yoda specifically. We can imagine what a 2022 CG model of Yoda would look like, but it’s not like we can describe the details of it, since it doesn’t exist.
Is there a fan that can show an example of what he would look like for example corridor crew?
You’d have to ask someone like the guys at Corridor Crew. But they’d need a reason to create that. And that would still just be a fan creation, and wouldn’t be up to par with what the VFX industry can create today. At best, it would only look slightly better than the prequel Yoda model, if even that.
I wish one the prequels were actually popular and two that Disney was the kind of studio that would update the prequels effects if it was oh well. 😦
