Hi Where do you find/see this? I just rendered the same AlexaLogC file to a linear EXR by setting the Read node to colorspace 'AlexaV3LogC' in Nuke8.0v6 and Nuke9.0v4b, and compared them in one of the Nukes. They are identical.
So you don't mean the actual curves in the LUT part of the project settings, right?
