The Blu-ray and 4K UHD release of Godzilla Minus One changed some of Godzilla’s roars (most notably when he is mutated by the Operation Crossroads nuke). In the original theatrical release, Godzilla uses his 1954 roar that is used throughout the film; but in the home media release, his roar is changed at some points.

The home media release only changes Godzilla’s roar in the Dolby Atmos and Dolby Digital EX 6.1 mixes, but the Dolby TrueHD/Dolby Digital 5.1 and 2.0 mixes still use the theatrical mix.

The alternate mix was also apparently used for the theatrical release of Godzilla Minus One/Minus Color, and it was apparently an intentional change, not a mixing/authoring error.
