Dan, my experience with LF lenses is quite a marked shift in colour balance between modern Multi-coated lenses and very early coated lenses, there's no doubting the bluse shift with my 1950's CZJ T coated Tessar it can be seen visibly as well as in colour images if no correction is used- I tested it in Turkey where the light's very constant in the Summer.

I've an early coated 65mm f8 SA (Linhof select) and that gives colder colours than my Multi coated Schneider and Rodenstock lenes, same lighting shot alonside on the same film stock, however later coated Schneider lenses are closer and it would be hard to tell between a coated and Multi-coated versions.
