Yes, but still with the same 85% quality you may obtain different
results by changing other parameters.
Just look at the following example. Note the file size for each, but
most of all, look at the color quality and the outline of objects
(the files are quite small; save them somewhere and look at them by
switching forth and back so you can notice the differences).
The JPEG were both saved with 85%, but one with subsample for best
quality and the other with subsample for minimum file size:
Take the .bmp and do further tests with the save options.
