Partially verified: the curator re-read S2, S5, S6, S7, S8; S1, S3, S4, S9 were not re-read by the curator and rest on the producer's pinned reading. Camera wide-gamut primaries are published unevenly. Blackmagic's DaVinci Wide Gamut document gives the xy primaries (red 0.8000/0.3130, green 0.1682/0.9877, blue 0.0790/-0.1155, D65 white) and matrices, and records a 2021 fix to the green x value. Blackmagic Wide Gamut Gen 4/5 and Canon Cinema Gamut primaries are easiest to find in the colour-science library, which cites vendor pages; Canon's white paper text has no numeric primaries. Sony's S-Gamut3 table exists only as an image in its PDF. Check any library constant against the vendor document where one exists.

Curator qualifications: Partially verified: the curator re-read S2, S5, S6, S7, S8; S1, S3, S4, S9 were not re-read by the curator and rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S1: HTTP 200, bytes equal to the producer pin; S3: HTTP 200, bytes equal to the producer pin; S4: HTTP 200, bytes differ from the producer pin; S9: HTTP 200, bytes equal to the producer pin. Documents and code read 2026-10-22; no conversion computed. Sony technical summary (raster primaries table) and the BRAW installer-bundled Gen 5 paper not read by the curator; forum post not re-read.

Limitations: Documents and code read 2026-10-22; no conversion computed.

Evidence status: curator/producer inference or synthesis from the cited sources (code read, not executed, where code is cited); correlated desk review (Claude); not independently reviewed.

Evidence claims:
- [inference] Camera wide-gamut primaries are published unevenly. Blackmagic's DaVinci Wide Gamut document gives the xy primaries (red 0.8000/0.3130, green 0.1682/0.9877, blue 0.0790/-0.1155, D65 white) and matrices, and records a 2021 fix to the green x value. Blackmagic Wide Gamut Gen 4/5 and Canon Cinema Gamut primaries are easiest to find in the colour-science library, which cites vendor pages; Canon's white paper text has no numeric primaries. Sony's S-Gamut3 table exists only as an image in its PDF. Check any library constant against the vendor document where one exists. · locator: cited at https://web.archive.org/web/20250920170411id_/https://pro.sony/s3/cms-static-content/uploadfile/06/1237494271406.pdf; Blackmagic DaVinci Resolve 17 Wide Gamut Intermediate PDF; colour-science datasets/blackmagic_design.py @e82dd14; colour-science datasets/canon_cinema_gamut.py @e82dd14; Canon WhitePaper_WideColorGamutsC500.pdf text layer; colour-science LICENSE · source: https://web.archive.org/web/20250920170411id_/https:/pro.sony/s3/cms-static-content/uploadfile/06/1237494271406.pdf
