My Sony TV is so so so so Terrible that it doesn’t allow many apps onto it.

I have a Sony Android 4K/UHD HDR with model number KD49XG9005.

can I sideload the Apple TV+ & BritBox Apps onto this TV? 

Sony should be ashamed of how they have treated this TV. It’s the worst purchase I have EVER made.

Sony seems to have abandoned this TV from any proper updates and use ability.

Also the HDR on this TV is the worst thing ever!!!!!  

so crap HDR & a lack of applications
