So if we ignore more than half the world, 50% of users still don't get those improvement. If you're under the impression that Google isn't able to properly track devices that hit play services, that's an entirely different and more worrisome problem.

The pretty large plurality (if not majority) of Android devices in the wild don't have have Google's services installed and many of those also get no software updates -- so they're stuck on what old ROM they came with, probably Lollipop.
