The results should be easily quantifiable if anyone wants to actually test it (QVC). But this phenomenon with Logitech's new G-hub software is exponentially worse than pre-G-hub software where even a caveman should be able to tell. It's like the method of writing data to the mice these companies are using is completely incapable of any deterministic behavior WHATSOEVER. Even if you're saving a setting of 800 DPI, sometimes it will feel slower and lagging behind, other times faster. So, I have always said that anytime you install mouse software and save settings to the mouse, it always gives you a wildly different result each time whether it's Logitech or some other company's software.
