Short answer:Yes. Long answer:YYYYYYYYeeeeeeeeeeeeessssssssss.
I've got some shots that were done with VS and Provia that are essentially identical, taken within minutes of each other. You really can't appreciate the difference until you see them side by side; it is like night and day. A warming filter definitely helps Provia.
I still have several dozen rolls of VS in the fridge and am making daily sacrifices to the Great Yellow God that the reborn Ektachrome will come in a VS version.
