Nuke - Color Difference with Transmissive Objects

Hi,

I'm having problems rebuilding an Octane Multipass Rendering in Nuke.

I followed the instructions from this site:
https://docs.otoy.com/StandaloneH_DEV/S ... Passes.htm

My node tree in Nuke is exactly the same and without transmissive Materials the merged layers look exactly the same as the Beauty-Rendering.
But with transmissive Materials, the transmissive Parts look slightly brighter. The Difference is very small, but if you open the scene in nuke, the difference is more obvious as in the picture.
What could be the reason?

I'm using Octane 3.07-R1 for C4D and I am rendering a 16-bit float Image with Gamma 2.2 and a Linear Response Curve.

I attached the exr+nuke file.

What am I missing in the Compositing Node Tree? Would be great if someone could have a look at it!
Many thanks in advance!
