This might be true for some apps, from the biggest developers. But even there, it only holds for a given point in time.
It's been shown time and again that developer support of past products is atrocious. You just can't count on getting your apps updated through the whole lifecycle of the device. This is partly understandable, as older hardware just isn't going to be able to handle some things (say, H.265). But even so, the developers seem to be doing little more than paying lip service.
The best strategy is to have a dumb monitor, and a device like Roku that you can upgrade very cheaply every year or two.
