DisneyPlus app streams in blue/green

I have the 4k box.  DisneyPlus 4k/HD streaming is suddenly being broadcast in blue/green tones.   It used to be fine.  I changed nothing.   Because of the colors I have tried rebooting the xfinity box, doing a refresh from the service menus, rebooting my Samsung S90C 4k tv, installing the latest software on my TV.   Nothing fixes the problem. 

The disneyplus app on the TV itself does not have the color problem but I don't use it much because my wifi isn't very good where the TV is located.   Usually just use the xfinity apps.

Anyone else have this problem.  Any solutions?   I cant see any way to uninstall/reinstall apps on the xfinity box...
