Moved from 6plus to 7plus, had the 6plus covered in heavy duty case with high dollar glass protector. The screen always had a lot of finger prints and the case decreases the appearance. Now have flat black and no screen saver. With just bumper guard around edges. The appearance of the 7plus is hands down looks great and the finish stands up great against finger prints and still retains the overall Beauty of the phone. Saved the money on protection which is better than what I would have made trading or selling out right. I agree with others that stated you really don't get that much if any value on case or glass to someone.
Have pics?
