I believe the volume sweep is a matter of the potentiometer. The volume sweep on a guitar could differ from potentiometer to potentiomer, even of the same brand and values because of the differences in tolerances.
But the treble bleed wouldn't affect the volume sweep, just the amount of high end that is retained when turning down the volume.
Actually, depending on the configuration and value of the components, a treble bleed circuit can have a noticeable effect on the pot taper.
If you're taking the time to tinker with these things to get the right performance out of your pot, another good option to consider is the "Gibson 50s wiring", where the tone control lead comes off of the volume pot output lug instead of the input lug. It preserves the tone all the way down the volume pot sweep, no getting muddy nor shrill at the bottom end, and has no effect on the taper. The downside, such as it is, is that the tone and volume controls interact differently when they are both rolled off. Takes some getting used to. It's a wiring mod typically associated with Gibson 2 vol/ 2 tone control schemes, but it's easily applied to Strats, Teles, etc. I use it on everything.
