For anyone without the time: my biggest takeaway when I first watched this was: audiences certainly like the idea of practical effects, so both media outlets and productions are incentivized to talk up every practical element, right up to the point of outright deception. In reality it's very common for stuff to be filmed "for real" and then painted over or extended with CGI anyways because having the reference footage helps the CGI so much. This way you can have your actors go on the talk show circuit and say "those are real tulips" or whatever and have good CGI at the same time.
