At Netflix a textless (or language) picture version is a supplemental IMF package built on the last approved texted package: its CPL reuses the same track-file IDs and adds one textless insert track, so unchanged shots are not re-delivered. SMPTE ST 2067-2 allows packages that are not complete compositions and ST 2067-3 defines textless marker labels (FFTC/LFTC etc.), but neither defines a 'textless version' as Netflix does.
