In Disney Gallery: The Book of Boba Fett, ILM Visual Effects Supervisor Richard Bluff detailed the changes made from Luke Skywalker's appearance in The Mandalorian Season 2 to The Book of Boba Fett: A new documentary special has documented the process for bringing Luke back into the fold in Boba Fett, including a comparison to the quality of his appearance in The Mandalorian.
As things would have it, those responsible for the hard work happen to agree.
Given how good Luke looked in Boba Fett, his deepfake in The Mandalorian has now been perceived as less than desirable by viewers.
