There's also a dynamic range benefit at higher ISOs. At base ISO, however, there's a dynamic range cost compared to the A7R.

This is devastating news to me. I am truly saddened to see this confirmed and thankful at the same time for the work you have put into it. I love everything about the A7S, but for practical issues on the job (for me at least) the A7 and A7R seem like the reigning champions, as I value low ISO DR above much else.

I don't know why people expect cameras with good very high ISO performance to do well at low ISOs -- that's really not how it works.

Simple answer, these were hopes/expectations based on the claims made by Sony. No need be confused as to "why people..."

I agree with you that the DR is still impressive, especially given the other features of the camera and sensor. I still bought it and am happy with it, so that outweighs the let down. But don't discount the let down that some people might experience in the face of a direct claim being shot down. The same would happen in other industries and lead to lawsuits for those who care to do that sort of thing. It doesn't matter that I am happy with the camera nonetheless. A company still is not supposed to make marketing claims they can't substantiate.

Whatever though, I am a happy Sony customer.
