$ screen --version
Screen version 4.08.00 (GNU) 05-Feb-20

Not a screen user myself, I just installed the latest screen from ports 
to check, and not seeing this behavior: without ~/.screenrc I get $TERM 
of "screen", and with "term xterm256-color" in ~/.screenrc I get exactly 
that in $TERM.

What are your other related settings? Or could it be stale system-wide 
configuration somewhere, stale patches?
