ssh -T has the desired properties:
$ ssh -T blood test -t 0; echo $?
1
$ ssh -T blood test -t 1; echo $?
1
$ ssh -T blood test -t 2; echo $?
1
$ ssh -T blood tput longname; echo $?
tput: No value for $TERM and no -T specified
2
Thus it can be used to test the behaviour of tty browsers:
$ ssh -T blood aptitude search --disable-columns "'-F%p %v'" ~i~Pwww-browser
elinks 0.12~pre5-2ubuntu1
links 2.2-1build1
links2 2.2-1build1
lynx-cur 2.8.8dev.2-1
netrik 1.16.1-1
w3m 0.5.2-2.1ubuntu1.1
Of all those, only netrik does what you seem to want -- exiting with a
non-zero exit status. links and links2 don't even exit, despite there
/dev/tty being inaccessible and /dev/stdin being at EOF!
$ ssh -T blood w3m http://example.net/ <&-; echo $?
