Disc rot does exist and it's a well understood phenomenon.
No, not every disc will rot. Most won't. But some will. And, yes, it is because of poor pressing, but it is nevertheless a very gradual process that can take years.
Just because there are CDs that are 30 years old that haven't rotted, it doesn't mean it doesn't exist.
Laserdiscs were particularly prone to it, presumably because of their greater size. I had first edition laserdiscs of Star Wars and The Omen, neither of which played by the time I finally gave up my laser disc player.
In terms of CDs, my first Silva Screen CD of Damien Omen II rotted.
I presume that in those occasions where you have to bend the disc nearly in half to get it out of it's holder, you increase the chances of breaking the seals slightly and letting the oxygen in.

I'm rather shocked that this wonderful set is suffering from a "disease" that I though was extinct.
I have not played mine in ages, because I have ripped the high-res audio files years ago.

The DVD-As and the Blu-Ray Audio discs have both HD 5.1 and HD stereo tracks. Would be shocking and obviously a mistake if the HD stereo tracks are upscaled?
My understanding from the posts above is that the DVD-A and BD discs are fully, native Hi-Res, and it's "only" the Hi-Res editon that out there for digital sale that's partially upscaled. Is that the case?
Yes, that's what I understood as well. What I meant is that it would be shocking and obviously a mistake if the HD stereo tracks for download are upscaled. Obviously, the HD stereo tracks exist and were already made for the DVD-A and Blu-ray audio disc. It seems like a mistake to sell upscaled versions of it as HD tracks. Well, either a mistake or downright fraud. :-)
Unless -- as it was Fellowship mentioned -- wasn't there some issue that some tracks were recorded with a different orchestra in a different recording venue? Not sure, it's been a while that I read about that.

Are these editions with the Blu-ray disc still available?

Another fail in the history of LOTR CR.
The official 24/48 Hi-rez version of Fellowship (available on sites like HDtracks and highresaudio) is 1/3 upscaled CD quality. Specifically disc 3 or on this release track 29 to 37.
For 30 euros you would think they could check these things.
What was your method to verify or question the integrity of the files?

Oomph! Is the one on Qobuz the same?
Qobuz has excellent customer service (in my experience) and they receive their files directly from the labels. Of course, labels sometimes provide faulty files.
They also say that: "we check the upsampling, upscaling and transcoding on all products delivered. The products are checked manually. If you have any product that you think are not correct, please provide me with the link."

So is HDtracks actually selling the legit 24bit 48kHz or that's still upsampling from CD quality?

And I'm looking at these sets now and backing up the CDs with Exact Audio Copy in flac to preserve them.
But for the DVD / Blu-Ray audio, are there any recommendations for backing those up?
EAC doesn't work with DVD or Blu-Ray and I'm finding scant info about preserving high-res audio from those discs outside of the menu-based navigation they use on-disc.

I just sampled some tracks from Qobuz's High-Res downloads with my own rips from the Audio-DVD from tracks like "Parth Galen" and "The Fighting Uruk-Hai".
The spectograms of the LOTR-FOTR DVD-Audio high-res stereo tracks are identical to the spectograms of the Qobuz high-res download.
