I have no doubts (hence my anecdata statement) that there could be bad DVDs in there, or that maybe over a longer time horizon that the media would be cooked.
After 10 years, which was longer than the assumed shelf life of writable/rewritable DVDs at the time, I never found a single corrupt file on the disks. They were stored in ideal conditions though, in a case, in a closed climate controlled shelf, and rarely if ever removed or used.
Also, just because I think it's funny, the archive was over 4000 DVDs. (We had a redundant copies of the data compressed and uncompressed, I think it was like 3000 uncompressed 1k compressed) there was also an offsite redundant copy we put on portable IDE (and eventually SATA) drives.
I made a pointless program to help w/ this on macOS for kicks: https://github.com/radiofreejohn/xattrkv
When I made it I also found a bug in the xattr implementation for Darwin and submitted it to Apple, they eventually fixed it.
I also wonder whose fpga core they are using and if they licensed it or not.
