It is possible that one version was created before some IBM PTF(s)
affected QDBLVLID, the routine that computes record format level
IDs.

The "DB" in QDBLvlId indicates the OS DataBase feature; i.e. for
Data Base Files, not Device Files for which the OS component/feature
is "DF". I recollect that the DB feature functions for, is invoked
for, *only* the creation of database files, and that device files
have their level-hash calculated within their corresponding /create/
program [or, but I think not] by a similarly separate
level-identifier program. [...]

Found the following on the web, a list [probably misappropriated, though I have often referenced, and been happy they are there] of OS program names with descriptions, that contradicts my thoughts [alluded above] about how DF generates their level identifiers [similarly to DB, in a common component program]:
