Whitepaper: 'If a display doesn’t support the HDR10+ metadata, it will be simply ignored as any other optional ITU-T T.35 metadata and the display reverts to show the strict version of HDR10'; carriage stated for 'HEVC and VP9 compatibility via WebM as well as any codec that supports ITU-T T.35 metadata'. S5: 'requires no licensing fees'. metadata.rs validate() ensures application_identifier == 4 and application_version == 1, so version-0 metadata fails validation when validation runs (code-derived inference, not executed); it also requires targeted_system_display_maximum_luminance == 0 when tone_mapping_flag is false (profile A) and non-zero for profile B. c3excerpts: 8/8 non-empty excerpts present.
