Not always, not for all the programs.  I don't think there's a way to do
what the OP wanted 100% of the time, at least not with ps(1):

$ ps auxww | grep -v grep | egrep -e 'xinit|screen'
root       604  0.0  0.7  3336 3004  ??  Is    2:24PM   0:00.03 screen -a -D -RR
root       615  0.0  0.7  3636 3304  ??  Ss    2:24PM   0:00.32 screen -a -D -RR
