> ... again and look for the PBKDF: line in each keyslot (pay attention only to the keyslots, ignore any references to pbkdf2 that come after the Digests: line). If the PBKDF is either "pbkdf2" or "argon2i" you should convert to argon2id

All good here then (Debian Bookworm default LUKS install):

    cryptsetup luksDump /dev/... | grep PBKDF
    PBKDF: argon2id
