Not only.

There is an UUID in the header of swap partitions (and files). Swap is
not a file system.

There is an UUID in the header of LVM physical volumes. PVs are not
filesystems.

Of course it does. MD raid devices contain both an UUID for the array
and an UUID for the device.

I will let somebody with more time than me to spend on find the right
invocation of lsblk or other to print both.
