Scoped negative. The Resolve 21.1 release page fetched here (49,818 bytes) mentions 'ACES Transform color space choices' but has no gamut-compression or RGC text. The Resolve 20 New Features Guide (already pinned) has zero 'gamut' hits; the Resolve 19 guide (already pinned) documents that an AMF look transform specifying the ACES reference gamut compress sets the 'Apply ACES reference gamut compress' checkbox, with no default and no ACES 2.0 mention (zero ACES 2 hits). The Resolve Reference Manual, Resolve 20.x read-me/release notes, and the Blackmagic forum release-notes thread were not read: the manual URL guess returned 404 and the forum thread returned 403 (access limit, not retried).

Curator qualifications: Resolve 19 has an AMF-settable 'Apply ACES reference gamut compress' checkbox; no default or 2.0 statement in pages read; manual unread (404/403).
