Am after a decent looking APK to use on various devices, android box, firestick etc .

I currently have tried all the usual ones, PP, IPTV, Xiptv, GSE and more and frankly they all look crap on a big screen, best I have seen is a one used by a USA serrvice called "Thunder TV" but when i trialled them , the UK Sports category wasn't even listed on the app so , I couldn't even check out their UK sports streams. Anybody know of any APK's that resemble sky or similar ? I also have an apple tv 4k , but have just about given up looking for an APK that I can install on that thats at all watchable.
