Thanks. Although Chapter 147 covers LUTs, it does not touch upon how to determine the input space requirements. It seems some LUTs have it documented in the .cube if you open it with a text editor, and others you seemingly have to either just know or find the creator of the LUT and ask. Obviously there's an opportunity for improvement in this area.
