The new My Cloud Home is not a traditional NAS. I think WD made it to be easier for users that are not familiar with NAS devices. this may be the case if you have never used a NAS but if you are familiar with previous My Cloud or other NAS products the My Cloud Home may be missing some things.
The My Cloud Home uses private user space for every different user. You do not have to create users, shares, and assign access permissions, all you need to do is invite someone using an email address. While this is easier the current implementation is a bit limited and although each user has their own storage space data cannot be shared between users. Some people from WD have commented this feature may be added in a future update but have not given any time frame.
The way it is accessed is different as well. The My Cloud Home still has a default share that is accessed via SAMBA which is a network protocol. This has to be there for things like Time Machine and Windows file history to work. The other way to access the drive is using WD Discovery. After WD Discovery is installed it will mount the logged in users private user space as a network drive. What is stored in the default public share and what is stored in the private user space are not using the same protocol and you cannot see data in both at the same time. This is why you see it listed in different locations on the computer.
Devices like your blu ray player are probably looking for network shares like the default public share and likely would not be able to see anything in the private user space unless there was some integration between WD and the Blu ray player manufactures.
I have both the old My Cloud (PR4100) and the New My Cloud Home Duo. They both are useful but they do have vastly different feature sets. I have found that I like the My Cloud Home Duo for some things like ease of data access. I can install WD discovery on any computer in out of my home network and the private user space will mount as a drive. Super easy access to the data from any computer I use with out having to use web access. That said I still rely on the PR4100 for managing multiple users and sharing data between them.
While the My cloud home does not meet all of my needs and I am glad I also have the PR4100 it has been perfect for my mother. I got her one of the 8TB single bay versions and she has had no issues syncing her pictures folder to the drive and sending share links to family and friends. For cases like that where you need easy to use functionality it seems to be a great fit but i realize it could be seen as lacking for other users.
