Not lost so much with those settings. The response curve of HSV ETM isn't the same as GC, but it has sufficient similarities to get you partway there. And if you combine that with a little shader GC, or just a touch of postwork GC, it looks pretty close.

The big difference is all the faffing about with shaders and postwork, versus just turning it on in Poser Pro.

Oh - and the big problem is if you also want to use IDL. The bounced light from incoming textures is wrong wrong wrong. They are too bright and the IDL gets thrown off.

The only way to get accurate lighting in P8 with IDL is to use shader incoming anti-GC, producing linear colors. Then let the renderer do its thing with IDL, and then do a teeny bit of outgoing GC in the shader, followed by HSV ETM. This will look within 5% of what Pro does automatically. it's a lot of work. For those who have more time than money, it can be done.
