The LLL (or at least my copy, but I think it's a characteristic of all, given it's documented in the spec sheet supplied with the lens by LLL) exhibits wavy field curvature in the shape of a 'w.'
I don't want to get in to a debate, and I didn't read your whole post, I just wanted to say - that even the Summicron Type 3 has this performace of the "W" your talking about.
It really is moot - enjoy the Summicron Replica. It behaves, 99.9% like the original design. It is the most practical angle of view, and a very well made lens.
Have a nice day shootin' 🙂
