Can I install the Play Store on my TV?

I have a Sony Bravia. Netflix, Amazon Prime and some other apps are installed on it, but I can't find a PlayStore. Is it possible to install it somehow or do I have to get a FireTv stick to install additional apps?

Playstore is already installed

And where can I find it?

You have to look at the apps. I also have a Bravia.

The playstore is not there with me

You only see it when you go to the settings. You don't see this as an app icon because you can't uninstall it. It comes with the television. At the top where the search bar is ect is very large APPS. If you click on it you are directly in the playstore
