But what really comes to mind when viewing the streaming version of Dune is the sharpness of the video. The blue eyes of the Fremen (which were more crudely integrated into David Lynch‘s version of Dune), are vibrant and convincing with Dolby Vision. On the visual side, the HDR delivered via Dolby Vision adds some good color depth to the video image. The Dolby Atmos soundtrack is riveting in its sound design, music composition from Hans Zimmer, effects, and wide dynamic range that can only be delivered with surround sound and a subwoofer to push those deep levels. You might even say the LFEs are as much a character in the film as Duncan or the sandworms when considering how much the deeper audio changes your experience of the film.
If you’ve got a subwoofer in place this movie sounds completely different with LFEs (Low-Frequency Effects) activated than it does without. The HBO Max 4k stream does offer a very good audio experience with deep-sounding effects that are out of this world. HBO Max’s stream of Dune (2021) in 4K with Dolby Vision and Dolby Atmos is impressive, but nowhere near reaches the capacity of the theatrical presentation or presumably what will be output from the 4K Blu-ray Disc.
