I don't using Opera Store for anything else. On my TV I can access it without going into opera, which is handy for my wife (less apps the better), but on my BDPS7200 i can only get it through opera, I prefer it on my blu ray player as I can get up to 7.1 through it.
Would I need to pay a subscription charge to use it on google play?
Do you even have android TV? If yes, then plex is/will be available via playstore.
If no then Opera Store will still work as before on SEN platform.
In any case you dont have to pay for anything (other than what Plex usually charge for some features).
