Provia 100F is my standard color film. I can't really speak to the others, except that the small amount of Provia 400 I've shot seemed generally similar, but a little warmer-balanced and of course with more grain. (E.g., https://www.flickr.com/photos/ntenny/5109364992/, though obviously it's hard to judge color balance from one uncontrolled image.)

I assume the underexposed shot is pretty dense-looking to the eye and you compensated in digital after scanning, right? I find the results are a little unpredictable in that process, depending I suppose on the lighting---in sunlight it often skews magenta rather than blue, in my experience.
