This is a candidate list for Perfect Release.
Mainly older titles either entirely shot on film and released from 1930 to 2001, but some post 2001 titles could qualify as well.
According to past releases, 4Ks released by Sony usually comes with original mix (or at least close to it), but their picture is usually more blurry and unfaithful to the original colors.
Universal's 4K also have the same blurriness problem.
Those released by Arrow have a high chance of including the original mix and more importantly well-compressed picture.
Criterion since around 2024 has been featuring good and accurate color grading on their 4K release, but the sound track is usually noise-reduced to some extent.
Shout Factory's image compression used to be not good but has been showing improvement recently.
Kino Lorber since 2025 is notorious for unacceptable image compression that are full of block artifacts. But fortunately they seems to be mostly free from blurriness, unlike others.
Other labels, especially major Hollywood studios are inconsistent.
(in the future)
basically any Arrow release, Ignite films, Celluloid Dreams, Indicator/Powerhouse and Radiance release unless specifically mentioned
