Quote -  Does Poser output (any format) conform to standards (is that ICC? or something like that?)

Short answer: no.

Longer answer: what you see on your monitor determines the choices you make with lighting, shaders, node values etc. So if you have a PC the chances are that an sRGB profile would be appropriate. If you have a custom monitor profile (one that you made using a monitor calibrator or a software-only utility) you should use that.

Quote - or is there a way to measure that/ assess that?

I have a long term project to create an ICC-compliant profiling solution for 3D apps, making very slow progress at the mo.

Meanwhile, you could try my Poser version of the MacBeth Color Checker here for assessing your setup.
