The Unity Recorder ProRes encoder hard-codes the Rec.709 colour definition; Rec.2020, PQ and HLG values exist only as commented-out enum entries, so engine ProRes output cannot be tagged for HDR or wide gamut. Whether written files carry tags was not observed.

Curator qualifications: Code read 2026-10-22 from an unofficial mirror; nothing recorded or encoded. Source is needle-mirror (unofficial mirror of the Unity Recorder package); byte identity with the Unity-distributed package not verified. Curator amendment CA-AM-0039 (2026-10-22): Scope note (curator, from C3R-0449 / C3-B222-G68): these statements are code_derived_inference from the needle-mirror source whose package.json matches the official UPM 5.1.7 registry metadata; file-level identity with the official tarball is unverified. Official Unity docs state none of them (no sample rate/bit depth; no PNG/JPEG sRGB forcing beyond EXR-only linear option; no ProRes colour definition). Cite them as code-level behaviour of the mirrored 5.1.7 source, not documented behaviour.

Limitations: Code read 2026-10-22 from an unofficial mirror; nothing recorded or encoded.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
