It's a Mag box.
It's mag box or stb emu app. With any iptv provider that offers MAC based subscriptions, you'll get this interface. Background colours might be different.

smart stb / stb emulator / MAG box for UI , iptv no idea
Magbox/ StBEmulator
Am using it , its STB-EMULATOR on a smart tv * LG or SAMSUNG * i use it with my SUB iptv007 and both are gr8 .

Looks like that’s a Mag interface. No idea on the provider though.
