I find the \texenginename and \texengineversion useful for retrieving

LuaJitTeX - unless I'm doing something wrong.
This is by design, see

For context, the most we benefit from luajittex is the lua vm speed and
not jitting. If you need to check for luatex vs luajittex then you're
doing things that are dependent on specific luajit features (like ffi)
and that's non-portable (platforms as well as the future).
