Leica Zeiss 35/1.4 & 85/1.4

Are these optically the same as the later Contax/Yashica and current Zeiss ZE and ZF.2?

I ask because I am considering either the outgoing ZE 85mmf/1.4 and the new Milvus 85mm f/1.4 for use on my Canon 6D. I own the ZE 35mm f/1.4 Distagon and love it.
I think that when using them wide open, the QBM versions will behave similarly to the Contax version, which may have more modern multicoatings. The QBM lenses have become cult lenses, regardless of their three aperture blades that result in strange looking bokeh. Modern Zeiss glass may be unmatched.
