Is this correct ? ACEScct to linear in Resolve 19.1.3

Is it correct that Resolve’s “Apply Forward OOTF” is the rendering used when converting from Scene Referred to Display Referred?
It is like RRT in ACES?

The purpose of an OOTF is conceptually the same as the ACES RRT – a rendering transform to map scene colorimetry to display colorimetry.

However an OOTF normally consists of a simple gamma function (often applied to luminance only – see the BT.2100 HLG OOTF, for example) rather than the more complex sigmoid curve and colour processing of the RRT.

The Resolve manual does not specify what OOTF is used.

It’s also worth pointing out that “RRT” is no longer a term used in ACES 2.0, with the rendering applied using a colour appearance model (CAM).
