Hola.
REAL 4K, NO FAKE 4K.
This is the real deal. Everything was digitally shot in 4K or the original 35/70mm film negative was scanned in 4K and all the mastering/editing was done in 4K. Typically, if the film has VFX it was rendered in 2K. Depending on the caliber of CG, the final picture quality might be imperceptible to Real 4K. Check the information below to see if the studios have upgraded the video with HDR or added immersive Dolby Atmos or DTS:X audio tracks.

Yo la he visto en mi proyector sobre 100" y la imagen es excelente, se perciben esos desenfoques como propios del fotógrama, nada artificiales.
Yo la vi en su estreno en el cine y os aseguro que no la recuerdo con esta cálida que ofrece esta edición
en 4K/HDR.
Saludos.
