It also occurred with 4K Blu Ray, which was a real pain in the neck on PC requiring Intel SGX, Intel Secure Media Path, and a billion other DRM things. Then Intel removed SGX in 11th generation onward, and the Blu Ray developers have basically decided that being unable to play 4K Blu Ray on modern PCs is apparently just fine and haven't done anything to fix that.
To this day, the only official way to play 4K Blu Ray on a PC is to get a 10th gen Intel and play back using Integrated Graphics using one of the internal drives made by a drive manufacturer who was utterly shafted by this nonsense.
(It's got to hurt more though that 4K Blu Ray's new and improved DRM was, despite all this, broken less than a year after release. If you are a drive maker, knowing your drives are useless on modern PCs because of broken DRM that Blu Ray developers still insist is necessary must be the most infuriating thing ever.)
