I can vouch that all the Netflix seasons were shot in the traditional MST3K Style. Servo flying and other things like the censor drones were shot practically. They were added in in post after the fact but Servo flying and Crow climbing the vines, etc were done live with real props, not CGI
Russ Walko, Erik Kuska, Tim Blaney and Carla Rudy help Servo fly during Season 11.
