The simplest woud be, I think, to disable your tone curve and see what happens to the histogram. Not quantitative, but it gives you a good idea. As you don't mention the camera you use, not much more to say. But you can always look through the basecurves provided with DT to get an idea how the one for your camera looks. Afaik, those curves are aimed to approach the camera jpeg as close as possible (ignoring the dynamic range compression tricks some brands provide). They are all more or less S-shaped, but differ quite a bit in final brightness and contrast.
