My main comments would be I would tend to aim 'contexts' being used as part of the complete viewing transform. Right now it reads as though we recommend having viewing 1D/3D luts per shot / context which I don't think is the case.
It would be great to restructure this a bit so the idea of contexts being part of the viewing transforms comes through.
eg a typical setup could be (order depending on the production requirements)
scene-linear
`- balance grade .cc or .ccc (Context Controlled)
`- creative grade .cc, .ccc or .spi1d (Context Controlled)
