You can use a 3D LUT but still have a reversible colorspace transform by defining both the to-reference and from-reference transforms (I.e to reference would use lab_to_xyz.lut and from-ref would use xyz_to_lab.lut)

So I'm trying to get my team off of doing so much in photoshop, and have written some tools using oiio to replace a lot of the workflow. Right now, they like to do an unsharpen mask in photoshop in LAB space on just the Lightness channel for some images.
I was hoping to represent this transform using ocio, but so far am at a loss. I can use a MatrixTransform to get to XYZ, but I don't want to use a 3d LUT to get to LAB because it needs to be fully reversible.
Is there some magic that I'm missing, or will I just have to do this in code?
