How old is Josy ? 35? Such cheekbones appear after 30.
It's about ugly cheekbones and strange old wrinkles that are not typical for young girls. In fact, it's about DAZ. Almost all the models in the game look 30+ and Bella seems to be the same age as Jill, lol. All DAZ models are quite low-poly and low-detailed.
This is not sculpting models with millions of polygons. Without hair, each model carries 30,000 polygons, which is not enough. For example, my camera model weighs more than 3 million polygons.
And accordingly, the lighting directly depends on the detail. The sun's rays are repelled from the surface, or rather from irregularities and roughness, and this affects the lighting of the scene as a whole. Accordingly, the fewer details on the model, the more plastic and unnatural the light will be. Detailing is added by sculpting when a large number of layers and clay are used, but all models of DAZ are flat.
In general, this is not a problem of DPC, it squeezes the maximum out of DAZ.
He probably started using subdivide more often when rendering, trying to add more polygons, but it's pointless. If the model is initially low-detailed, without any inherent human irregularities, you can add as many polygons as you want, but you will not be able to make the model better.
