From what I remember, you can do this if the transforms are analytical. If you are referring to a baked in file based one then you will have to provide your own from for that.

I am a developer of Krita  painting
application and we use OCIO for displaying wide range images. I'm having
a bit of a problem now. Since we are a painting application, we need to
be able not only to display a color on screen (which we do using
DisplayTransform), but also to pick an already displayed color back into
app (for usage in color selectors or for drag-and-dropped colors). So,
effectively, I need to get a reversed transform for a DisplayTransform.
But it seems to be explicitly prohibited (it throws an exception in the
case). I'm wondering, is it possible to get a reversed transform for a
DisplayTransform without reimplementing it completely using
Thank you in advance!
