I think the general consensus is that unless you own an OLED (in which case you want to stay in the native environment for the features that will help preserve the display's longevity), it's better to grab an Android TV box and run everything through that. If you have a Z9D, I'd say it's getting old enough that that would be a decent route to take (since otherwise it's still a better TV than pretty much anything out today).
