No it isn’t. Olejellylegs wrote, “the open matte version of the film where only digital shots are cropped”. In this the open-matte scenes are uncropped (the editor hasn’t yet removed the top and bottom of the frame to make a widescreen final shot) while the CGI scenes are cropped to widescreen (because they’ve been through the optical printing process to render the CGI back to film, and lost the extraneous tops/bottoms of the frame in the process.)
