Yes, that's often the case.
There are often all sorts of technical mistakes because people who are competent with video and audio are rare. Most who are actually doing the job for the companies selling disc releases are incompetent and either apathetic or satisfied with saying "it's subjective" and then half-assing it.
Most photographers don't know how to take a picture, and even those who know things like aperture think they're knobs you twist until you get an effect rather than tools for squeezing the most accurate picture out of the camera. You can expect the same thing out of people dealing with video and audio.
There's also the issue of corporate culture where they will use the corporate product to get the job done, which is rarely any good.
The disc standards are very horribly made and easy to mess up. For instance, DVD has no progressive mode, there's only a word-of-mouth standard where you telecine progressive footage and hope the player either figures it out (telecining can be detected, but also misdetected) or your DVD sends the player some sort of proprietary signal. DVD is a literal computer that you can program with a special assembly language, this assembly language is how DVD menus and unskippable copyright notices are made. DVD also has rectangular pixels. This and more creates a lot of traps that the great majority of DVD makers fall into.
Then there's the issue of remastering the film correctly. Whoever remastered Evangelion for instance forgot to calibrate the colors of the tool they used, and the resulting image is tinted.
And there's the issue of preserving the film. If you store it poorly, it will deteriorate.
As you mentioned there's the misguided filtering.
For broken disc relases, see: Dragon Ball, Crusher Joe, Legend of the Galactic Heroes, Slayers TV series, Evangelion, Saint Seiya, Excel Saga, Sailor Moon (there's a DVD release that's actually good, but the blu-rays suck), Dirty Pair, Terminator, Star Wars. I have a general feeling most home video releases are bad, certainly most of the ones I watched.
There are good disc releases however, and there are fixable releases also. A lot of pirate encoders fix mistakes in the official release, one such release for instance is Evangelion. There are multiple fan encodes with the color issue fixed.
I mostly watch anime, I know at least 2 good western releases, but I think those are the only ones I ever watched that were good.
For anime there are so many I can't recall all, for good or fixable and fixed in a pirate encode releases check out Terra e..., Lodoss, Gunbuster, Maison Ikkoku, Escaflowne, the original Tenchi Muyo OVAs, Urusei Yatsura, Slayers OVAs, Macross, Tokimeki Tonight (actually a web release), Arion, Iczer-1, Megazone 23, Magic Knight Rayearth, Angel's Egg, Kimagure Orange Road.
Beware incompetent pirate encoders also exist, and they can make poor encodes or filter the image. All the fan encodes of Urusei Yatsura are heavily filtered for instance.
There are 2 funny trends I have noticed. First, some movies are so old that the makers had no chance of butchering the image, they didn't have computers to do it with. Filtering an image in the old days was putting a red glass pane in front of the prism you're burning your image into the film with so it's tinted red.
If you look at an old movie like 2001: A Space Odyssey or Back to the Future, the image couldn't possibly be desaturated until it was composed of dark shades of bluish grey like a modern movie. They didn't have a computer to do that with. The colors are all perfect, and those movies also happen to have actually good blu-ray releases that are true to the original.
Second, some movies have only ever been released in good quality on analog cinema. From when cinema video was done with a film roll and a projector. There's even a project trying to create a fan remaster Star Wars from old cinema reels https://www.thestarwarstrilogy.com/project-4k77/ because all the official home releases are terrible.
