The amount of very cool stunt work being done in the movie doesn't change how much CGI is in the movie. Per the VFX supervisor Andrew Jackson, there were 2000 visual effects shots in the movie.
And per the director of photography John Seales, "There was an enormous amount of green screen. The 40 to 45 percent of the film with the beautiful Charlize Theron and five beautiful girls in the backseat who are all involved in getting that truck to a certain point and back again is done without the truck moving. The visual effects boys built big hydraulics rams and could put the entire semi-trailer tanker onto rams and rock that thing."
Do I think Furiosa's look is occasionally more artificial than Fury Road's? Sure. And it certainly has much more CGI, I'd think, given how much longer the movie is, so maybe the budget was stretched for certain shots. But just for the record, Fury Road has a ton of CGI in it.
