Is it possible to apply a look as well? Would that require adding a colorspace to ocio.config? Or is it even possible?

If you look at the spi-vfx configuration, the srgb8 and p3dci8 color spaces incorporate a film look using a 3D LUT. That's why you can use them as an output space but not an input space (the 3D LUT can't be inverted). To do different 3D LUTs for different shots with the software as it currently is, you could create a whole bunch of output color spaces (srgb8-shot1, srgb8-shot2, etc.) as Ben is suggesting.

OCIO has the ability to add a separate "looks" parameter via DisplayTransform.setLooksOverride() and other mechanisms, but none of the current software is using it and none of the sample configs have looks. I'm kind of surprised by that actually - does Sony not use per-shot color corrections and looks?
