I'm unable to replicate this.  here's a transcript of my session,
testing pinentry-qt 1.1.0-1+b1 and gnupg 2.2.10-1 on debian
testing/unstable:


0 dkg at alice:~$ DISPLAY= pinentry-qt 
OK Pleased to meet you
getpin
D monkey
OK
0 dkg at alice:~$ DISPLAY= pinentry-qt --display :0
OK Pleased to meet you
getpin
D monkey
OK
0 dkg at alice:~$ unset DISPLAY
0 dkg at alice:~$ pinentry-qt --display :0
OK Pleased to meet you
getpin 
D abc123
OK
0 dkg at alice:~$ pinentry-qt 
OK Pleased to meet you
getpin
D abc123
OK
0 dkg at alice:~$ 

The two entries with --display caused a graphical display to pop up.
the other two caused the curses fallback.

if you can sort out a clearer replication, please report it on
