Bridgestone T31 - yellow dot is the HEAVY spot? WTF?

I have had the exact same experience as you of never having wear or vibration issues, and I don't bother to balance my tires at all, so no issues doesn't really mean the dynabeads are doing anything.

To actually test them you would need to get a wheel far enough out of balance that it was noticeable while riding and then add the dynabeads to see if they make it better

Not the case. Beads are not always in optimal balance position, it takes about a second. I can feel them causing imbalance when hitting bumps and starting from standstill (lesser amount). Might be less with perfectly balanced wheel to begin with, but even then, they're some wobbles due to their dynamic nature. For most people, 80% is good enough.

OR, you could actually TRY hem and see if the REALLY work? Do you 'Nay Sayers' have any actual experience with balance beads? If so, please regale us with your experience and wisdom.

Without searching for the tests, there are plenty of well done tests that say they are useless and actually cause problems.

If they actually worked as promised by the manufacturer, why, then, does no vehicle manufacturer use them?

That doesn't show they are helping though, just that they add some wobble when you start rolling. Unless you test without the beads you can't know if the tires would be totally fine without any sort of balancing.
