I thought an app could load more assets (from iCloud) after the inital 200 MB max. download. AFAIK, the downloadable assets are managed into some kind of pool to avoid the ATV would run out of storage. So, if a running app needs assests, assets from non-running apps are "paged out" (removed).

Wrt advancedsettings.xml, so you moved the buffer and redraw stuff to formal GUI settings ? Finally !! Hopefully this will end up into Kodi as well. Fixing buffering issues on e.g. the Shield is PITA.

There is no iCloud Documents present on the ATV4, only iCouldKit and it is a pain in the ass

Buffering is one thing that will not move, it's a hack and hides the fact that the entire kodi buffering scheme is broke. There are already way too many 'buffers' internally and they all tend to fight each other.
