What's going on with G9 surfaces and Subsurface?
The 1st image is a G9F skin texture created using FaceGen and the 2nd image is after loading the G9 Feminine Skin Mat to obtain the extra surface nodes. All I did was replace the skin textures from before. Settings for "SSS Enable" are the same for the head, body, legs & arms. I can't figure out why the texture for the arms aren't displaying properly in Iray when the rest of the textures are working just fine.

In genral this would be a question about a piece of content, not Daz Studio, and so should be in Technical Help. However, I suspect there is a generic DS answer - one or more of the textures on the arm has a different gamma setting from the equivalent maps on the rest of the figure. You can see the gamma value by clicking the nano-thumbnail next to a proeprty with a map in Surfaces pane>Editor tab and selecting Image Editor (not Layered Image Editor).
