I don't doubt that for a moment, but I'm fascinated now why that should be. I mean, I can think of a few advantages of having a curved blade, but I can't think why it would be that the curvature alone would make it wipe better than a straight blade, except maybe if by being curved, the increased vertical distance between the middle of the blade (ie the peak of the curve) and the ends of the blade, create a more rigid structure, one that is less prone to wobble/judder as it moves across the windscreen.
Other than that, I would imagine the curvature would have the cosmetic advantage of bringing the tip of the n/s wiper closer to, and more inline with, the bottom edge of the windscreen. No doubt the curve also reduces the overall effective straight-line length of the blade, but if that were the only advantage, a shorter straight blade would be just as good.
