No, the future import has no impact on b-strings.

-----snip snip-----
from __future__ import print_function
import sys
print(sys.version_info.major, sys.version_info.minor, type(b''))
-----snip snip-----

$ python /tmp/foo.py
2 7 <type 'str'>
$ python3 /tmp/foo.py
3 2 <class 'bytes'>

from __future__ import print_function, unicode_literals
import sys
print(sys.version_info.major, sys.version_info.minor, type(b''))
-----snip snip-----

$ python /tmp/foo.py
2 7 <type 'str'>
$ python3 /tmp/foo.py
3 2 <class 'bytes'>
