I've tried a bit to do the same thing. When you export a lut from DaVinci, there's the cube lut (3d) and what they call a shaperlut (1d). From what I understand the shaperlut 'shapes' the data so that the 3d lut transformation is less extreme, ie the shaperlut brings the values closer to their destination, then the 3d lut is applied to finish the job. Problem is that we cannot load those shaperlut's in Nuke. But apparently they are close to a log2lin transform (or the inverse). So load the ungraded footage in Nuke, apply a log2lin, then apply the vectorfield node with the cube lut. In my experience this got me a close result. Hope this helps.
