I am sorry for this merry go round...
I figured it out lying in bed last night, and only just remembered... Dxo Pure Raw and Deep Prime processing...
The White Balance is set to the same for all these photos 2750 / +4
The DXO files are a little greener on the 24-70, a little pinker on the 70-200
whereas non DXO look quite a good match.
I've submitted a ticket to DXO

I'm a bit late to this, and I've only skim read your posts, but if this is a consistent problem with your lenses, I think you may be chasing the wrong thing by looking at white balance because you may well be seeing a "colour cast" caused by the lens. Which although affecting the overall colour, is unrelated to white balance.
The different types of glass used in a lens and the lens coating can result in lenses having different colour casts. In theory the lens coating should correct this colour cast, and different manufacturers may have their own distinctive, and consistent, cast (e.g. in the film days with Kodachrome, Nikon lenses were slightly pink and Canon lenses slightly green).
This was, and still is, a particular problem with large format cameras where you could easily be using lenses made by a range of different manufacturers e.g. Nikon, Fuji, Rodenstock or Schneider (plus others) all on the same job. Although you would normally expect lenses from the same manufacturer to have a matching colour cast, this isn't always the case, and lens vignetting can give a different colour cast across different parts of the image, as can different lens ranges from the same manufacturer, which may have different qualities of coatings.
Currently, my single Zeiss Lens gives a distinctively different (cool) colour cast when compared to my old (warm) Nkkor lenses, and they, in turn, give a different colour cast to my modern (cooler, but not as cool as the Zeiss lens) Nikon lenses. I never use auto white balance, so this is a difference in the lenses. Personally, in my landscape pictures I just ignore these differences as I'm not doing anything that requires precise colour matching. Once upon a time when I was doing scientific/technical photography it mattered, but not now
Capture One has tools to correct lens colour casts, and although not directly relevant it may be useful to see what they have to say. It's primarily aimed at correcting vignetting effects with large format lenses but if you read more about it, people use it for much more than this, including as a general purpose method of correcting lens colour casts.
I'm no expert with lightroom, but I would have thought the "color calibration sliders" in Lightroom might allow you to make colour profiles for each of your lenses.
It might be worth googling "lens color correction+lightroom +color calibration profile", or something like that, and see if anything useful pops up.
But if you have sorted it out, just ignore me
