Still looks too digital. Too much contrast.
The *REAL* 8 mm looks like this

I was not trying to make this look like any film stock. I was trying to reproduce the natural range of color and value my eye sees in the scene. Difficult as the range of light values by my meter is between 13 and 14 stops from the outside specular highlights to the deepest shadows on the dark wood.
There is still room to flatten the image contrast considerably but it that brings noise levels up too. The outside highlights are clipped by about 1 stop. Resolve's soft clip function is nice for smoothing digital highlights.
This doesn't look so much like S8 as 16mm film.
