What does Android's public camera documentation say about RAW capture, colour metadata and 10-bit/HDR video, and does it define a log profile?

Android's Camera2 API gives RAW capture as a 16-bit mosaic plus the metadata to decode it (black-level pattern, white level, per-illuminant colour matrices), and DngCreator writes a DNG from a capture without extra setup. For video, the dynamic-range profiles are standard 8-bit, HLG10 (required on all 10-bit-capable devices), HDR10, HDR10+ and Dolby Vision variants; API level 37 adds SMPTE ST 2094-50 Dolby Vision modes. There is still no log profile (page last updated August 2026). Vendor log curves like Xiaomi Mi-Log are documented by the vendor and implemented in colour-science.
