Question about Sony Ubp-X700

Only the options remove, move, register as favourite are available. In principle, the content can be "mirrored" from the smartphone/tablet to the device so that the content of the desired app can be displayed via the app in the smartphone. However, this is almost certainly associated with a loss of quality. If necessary, the app can also be loaded directly on the TV ?

I have not found any options to download other apps.
