lets put it out raw for this one my friends. the disk encryption is whole disk encryption which means the encryption is effective when OS is not booted.
Once you enter decryption key at boot time for OS its just like normal OS for OS its all decrypted / plaintext. this is effective if someone takes a memory dump of your phone he will not be able to recover anything. I hope that sets it clear for you.
