For the volume, no it wouldn't matter. But wouldn't it matter for the water column height to be right in the vial itself since "more height" will yield a darker colour, "less height" a lighter colour, thus throwing off the readings?
The colour comparison things are at best a subjective leap anyhow ("Is this shade of pink more like that hue, or this hue?"). I wish there were more titration type test kits since there's no guesswork involved with those, just counting drops until you see a colour *change* rather than guessing how pink something is. I've never heard of a titration style testkit for nitrate though, just for calcium and alkalinity.
