Complex IOR fresnel different from standard_surface IOR?

I'm seeing a difference between using the standard_surface IOR and using the complex_IOR node. The facing value seems correct, however the values start to differ when approaching the edges.

standardsurface IOR 1.5:

complex IOR:

The images show the standardsurface with spec only, roughness to 0, spec color 1 and a constant white dome env & the complex IOR with n 1.5 and k 0 directly connected to aiUtility in flat mode.

This is a bug. The aiComplexIOR looks like the one not correct.

Cool, good to know! Hopefully it will be fixed in an upcoming version.
