You are right, of course. To be even more pedantic, eMMC is a different standard, though they overlap on basic operations. Most of the eMMC I've encountered come from the mfr programmed to their erase value (usually, oddly all 0's despite what we know about flash). In post-production, however, they're often written with data, so by the time you get to them, they're usually not blank.
