I have a question about calibration in Rock Band?

So I'm a drummer but I got a PS4 guitar controller just so I could calibrate my settings in Rock Band 4. I was wondering if the settings are just TV specific.

I was using my parents' old TV for Rock Band 2 and 3 and I don't have a PS3 guitar controller so I cannot calibrate my settings in Rock Band 3 via guitar on my PS3 but I didn't need to back then. Now I have an HD so I do need to calibrate the settings. I know that I can select the MS manually and I was wondering if I could just take a picture of my settings in Rock Band 4 and use those same settings on RB3 because I would love to play Rock Band 3 again. So if I calibrate that game manually, would the same settings I use in RB4 work on the same TV?
