No, it fails if the argument is both a function AND a variable.

imadev:~$ is_defined3() { { declare -p -- "$1" && ! declare -fp -- "$1"; } 
2>/dev/null >&2; } 
imadev:~$ declare -p foo
bash: declare: foo: not found
imadev:~$ is_defined3 foo ; echo $?
1

So far, so good.  But....

imadev:~$ foo() { echo foo; }
imadev:~$ foo=bar
imadev:~$ is_defined3 foo ; echo $?
1
