ocio includes lut's for converting a legal rec709 curves.
>From inside the ocio.config file with the spi-vfx profile it looks like
they do these operations:
- !<FileTransform> {src: hdOffset.spimtx, interpolation: nearest,
direction: inverse}
- !<ColorSpaceTransform> {src: vd16, dst: lnf}
You can find all the ocio lut's here:
/Applications/Nuke6.3v8/Nuke6.3v8.app/Contents/MacOS/plugins/OCIOConfigs/configs/spi-vfx/luts
