Also wondering about this same film, as well has No Way Home. I've seen a few IMAX hybrid releases where the uploader credits the DV layer from a non-IMAX release, and am unsure how this is possible. Can non-IMAX Dolby Vision sources create legit IMAX hybrids? To my knowledge neither FFH nor NWH have IMAX DV releases.
(Note: I am not talking about generating it yourself with Davinci Resolve or some other method.)
