[linux-lvm] discard with luks and the FS itself

[Sven Eschenberg]

Depends on your storage stack configuration, but the answer is mostly yes:
cryptsetup has discard disabled by default, for very good reasons.
filesystems vary, so you'd have to check on your particular filesystem 
documentation.

That's probably why you cannot find the ultimate answer - there's none.
