I would start by using the Resolve feature of Scene Cut Detection on the Media page to import the master file. This should accurately chop the master into individual shots. Place that on the top track of the imported AAF timeline and then identify the shots that group with a particular camera & scene. If you color code those clips, then on the Color Page, you can select clips by color and put them in a group. If you then apply a color space transform to that group, post clip grade then you can get each camera in the correct color space but still be able to apply grades pre the transform. I prefer that to using a LUT but if you want you could put a LUT post clip grade, but not before or you will bake it in.
Where you have dissolves or other transitions, you should have them as a single clip which makes it difficult to manage color space if a transition goes between different cameras. You will need to keyframe grades across transitions. I certainly hope you got a file that was textless otherwise your grades will also bake into the text.
