Geektastic:Mine updated a week or so ago but frankly it looks the same and since I have yet to change anything from out of the box I can't see it will make much difference to me what they load as long as it runs properly!
It probably isnโt the update to Oreo, the home screen on Oreo looks significantly different to Nougat, plus Oreo isnโt available for NZ yet so you can expect another update for your TV over the coming weeks.
