It can be hard to find full 4k atmos versions online in my opinion. But usual benefits are the same for any physical collection. Actually having something tangible you can look at and touch and know you’ll always have as long as you look after it and disc rot doesn’t come for it before your own demise.
For FHD Blu-Rays yes (though IIRC you need to download a file with the list of AACS keys for decryption). For UHD BluRays, you need to get a drive that people have made a custom firmware for and flash the firmware first. This is because UHD drives also have hardware level encryption protection that prevents you from being able to read the discs directly (assuming the firmware is working as intended, hence the need to flash a custom firmware). Realistically, just find a remux torrent. It’s much easier.

Back up your physical media!!
Can’t you just get the BR-ISO and remux yourself?
