Smart TV has various applications available based on each region where it is sold. TV devices sold in any other regions than USA usually don’t allow you to change the region to the US. On some Smart TV devices some applications may not work. This is probably because Samsung locks down various apps by the TV model number, as model numbers in the US are different from those elsewhere in the world.
Changing the region in your TV will allow you to switch the US and UK regions for multi-regional websites and also will help you in the future to change other application’s/website’s regions.
