Even so, a 1/3 stop difference is very small!

Perhaps very small with negative films, but IMO it's not all that small with transparency. It's at the edge of forgiveness in exposure error. Shift it much more and there are potential issues with highlight detail to cope with . . . the final decision of course to be made by the photographer about what's important in the scene and what needs to be preserved.

As an aside, under-exposing Velvia would tend to saturate it even more. Certainly there are those who might want this at the expense of shadow detail, but strongly suggest experimenting with it first and bracketing critical shots until experience with cause->effect in what it creates is attained.

Who's not certain why someone would want to saturate Velvia further, but it's all in the photographer's visualization for the desired result.
