Nah, I wouldn't say that. Maybe other experience and knowledge
The quick explanation for SubD or subdivision level is: It increases the amount of mesh polygons of the model, so that finer details like wrinkles can be displayed and rendered. In DAZ, you can change the SubD level of yout figure in the tab "Parameters" > "Mesh resolution". If you set the resolution level on "High resolution", you can select the SubD level for view and rendering separtely. Depending on the figure, default is 3 and it can go up to 4 or 5. So in conclusion: The higher the setting of the SubD level is, the more details can be displayed. But more polygons in your scene will increase the estimated rendering time enormeous.
