I don't *know* the answer, but my suspicion is that this is related
to very old compatibility code in the bowels of vim or its dependent
libraries (including other things in the call stack including getty),
having to do with terminals that are not capable of handling
lower case letters.
A piece of history: Years back, there were upper-case-only terminals.
Later there was mixed case, but enough of the upper-case-only ones that
UNIX needed to allow for it. For example, at the login prompt if you
put your login ID as all upper case the terminal will default to all
upper case (and do some case conversion of your password as well, iirc).
My suspicion is that since vim is detecting that its input is not a
tty, something in it or its libraries is reverting back to this old
behavior. However it's been so long since there was a signficant
(or any?) user base that used this feature, vim's capabilities in
this respect have suffered from bit rot due to lack of testing this
