final Cellebrite Premium ES is only available for law enforcement or companies like Ontrack can buy a package ?
So from my understanding, Premium allow limited or unlimited unlocking (iOS, Android) depending on the package you bought (core, pro, unlimited) + more phones support for Physical extractions through vulnerabilities (EDL, bootloader, MTP) and full file system extraction for recent iPhones.
UFED 4PC is more likely for consent extraction and physical extraction is limited to some old non encrypted device.
