Note that MakeMKV will not rip Super Audio CDs. As far as I'm aware there are no drives, and no software, on PC that can rip the format. There are mods/hacks for certain set-top Blu-ray Disc players that support SA-CD that will allow you to dump the content of the SA-CD disc, but it's really out of scope for MakeMKV.
Anything that's just a Blu-ray Disc, MakeMKV should be able to handle. "Profile 3" is just a subset of the normal Blu-ray Disc format, so any audio-only Blu-ray Disc should be rippable with MakeMKV.
To add to the previous, excellent posts, you should make a non-encrypted backup of your bluray audio disc. Then, use your favorite software on those files to 'rip' your 2.0 and 5.1 PCM files. I use DVD Audio Extractor and it can tried free for 30 days. For DVD-A discs, you don't need MakeMKV at all, only DVD Audio Extractor. SACD is pretty easy once you get the script on your thumb drive and software on your PC (Google how to set everything up as well as get the software/script). You only need a cheap, $15 - $20 Sony bluray player to convert all your SACDs. Hardest part is adding metadata and album artwork, but even that takes little time once you've done it enough times.
