I tried recovering a bad bluray with aaru, it was able to create a partial dump but I wasn’t able to fully read it. After about a week of churning it was still picking up more sectors but even if it might have gotten it in time I didn’t want to work my drive that hard.

I ended up finding a working copy of that movie at goodwill, but I still have other discs not reading. I decided it isn’t worth going beyond what you described, at some point the disc is just genuinely bad.
