Maybe Umbrella Australia 4K Blu-ray (FiM encode), Plaion Germany 4K Blu-ray, or Pony Canyon Japan 4K Blu-ray. All other existing 4K Blu-rays have terrible compression: https://forum.blu-ray.com/showpost.php?p=21423337&postcount=173
The master is heavily DNR'd.
4K Blu-ray caveat: mostly great video but the 4K Blu-rays have had additional DNR applied in some scenes on top of the DNR that had been applied in post-production and was already present on the DVDs & Blu-rays

2024 Mercury 4K Blu-ray
(But has obvious DNR, especially when the camera is not in motion)
Director: Christopher Nolan
Caveat: mild DNR throughout the transfer, non-IMAX scenes appear soft due to being scanned from an interpositive rather than the original camera negative.
Directors: Michael Spierig & Peter Spierig
Umbrella 4K Blu-ray is reported to have a different, more organic-looking master without the DNR on the Lionsgate 4K Blu-ray. Encoding and possibly further mastering by FiM. Still “just” an upscale.
Caveat: mild DNR throughout the transfer, non-IMAX scenes appear soft due to being scanned from an interpositive rather than the original camera negative.
