There is no official "4K Blu-ray" box set released by Disney/National Geographic for Cosmos: A Spacetime Odyssey (only standard Blu-ray). However, Cosmos: Possible Worlds (the 2020 sequel) is available in Native 4K Blu-ray.
Cosmos: A Spacetime Odyssey is not merely a lecture series; it is a visual symphony. Produced by Seth MacFarlane, Ann Druyan (Sagan’s widow), and Brannon Braga, the show blends live-action, CGI, and illustrated animation.
