I haven't looked in detail at exactly what needs to be adjusted between Truelight and Resolve LUTs, but my point was that the actual 3D cube values are the same for both formats. The differences are just text formatting. One thing I do recall is that the Truelight format uses a different ordering of R, G, and B on the line than every other LUT format.
For a 3D LUT of order 17 you'd have 4913 (17^3) points, each with an RGB coordinate. As I recall the Resolve uses order 33, or 35,937 (33^3) points. (LUT sizes are typically powers of two + 1. By making the size odd it ensures that there is an exact center point which would represent neutral gray.)
The ASC CDL is limited to lift/gamma/gain/saturation, but that's 90% of grading. It's not useful for monitor calibration, though.
