From what I understand the base table is a set of hue sat values designed to work with the RGB matrix coefficients to produce some colors that match what would be expected for the embedded illuminant value …many DCP have 2 illuminant values and hence tables and the other WB values are interpolated…the tone curve is used to tweak the Look of the color but produces shifts so a custom lut is included to balance that…I believe it in not recommended to turn one off or on without the other…having said that the DNG converter…has general and camera styles/profile DCP files for a wide range of cameras…essentially equal to what you could get in Adobe Camera Raw and you can see the nuts and bolts of these using the free Adobe DCP profile editor including adding embedded curves of your own design…so the comment above about not being able to control the output is not entirely true on that front when using DCP files and a review of the discussion of profiles on the dcamprof website illustrates the workflow to create DCP files to achieve a certain look…so there is indeed some tweaking that can be done esp if even after you calibrate things maybe you say don’t have exactly the red tone you are looking for or you want to tweak your colors a bit for effect you can visually edit your DCP file and save it using the Adobe editor…not for everyone but some may want to play around with it…
