The following observation might help: \everyjob is put into the stream
before whatever comes next. So it can know what's coming, either \input
or anything else. If it is \input, then it just has to use one
\expandafter before doing what it is supposed to do, and \jobname is
correctly fixed.

For instance, try "lualatex \input test" with the following in the
format (e.g. replaced lualatexquotejobname with that code):

\makeatletter
\long\def\getalook{%
\immediate\write0{\jobname}%
}
\everyjob{%
\let\input\@@input
\expandafter\getalook
}
\makeatother

Then "test" is printed to the terminal, because the expansion of
\jobname happens after \input. Remove \expandafter and you'll get
"texput" instead. Here I've restored the primitive meaning of \input to
make life simpler, but that'd work with LaTeX's \input and a subtler code.

Best,
Paul
