I haven't seen this mentioned anywhere, but the Computers / Home Sharing app on the ATV 4 has received a total facelift in tvOS11. Previously it looked pretty much identical to the ATV 2 & 3 but the new version more closely resembles the layout of the TV Shows and Movies apps. The Music section of the app also was updated. Gone is the focus on text lists, replaced by cover art. A long overdue update and encouraging to see Apple put some resources towards the Home Sharing feature of the ATV.
