Why can't I find the apps of my choice to download from LG WebOS?

I downloaded an app called SonyLIV to watch movies and cricket in India. As they host from India, they have geographical restrictions. To access them, I’m advised to download and install an app called ‘PureVPN’. This app is not downloadable from LGWebOS TV.

Why can’t I find this app? How is the decision made on what apps should be available in LGApp store? I’m an unhappy customer of LG.
