eMMC usually has csd and ext_csd registers that tells information regarding wear level and such. It's easy to access these from Linux, but not sure how we would do it on Android.

You can build/install mmc-utils on the device (even from Google's repo,[1] if outdated) but can't access the storage device paths without root. If you're on a custom ROM, the mmc command might even be part of it.
