Should be a two-step/node solution: - import it with colorspace set to linear (to avoid any conversion) - add a Grade node, set the blackpoint to 16/1023 and whitepoint to 940/1023 (this expands the limited range to full range) - add a colorspace with 'in' set to 'rec709' and 'out' set to 'linear' (removes the rec709 gamma)
if you want to put this into LUT, use the CMSTestPattern, apply the nodes above and export a LUT with the GenerateLUT node.
