At least with fridges a screen is extra cost to be built in. On other hand with TVs unless you are doing just a monitor, you need something to control it. And I mean like digital TV, selecting input, possibly show some overlay or controls. And at that point just slapping a computer in it is lot faster development cycle. And then you might as well support streaming services as general population seem to want those.
