The worry I have with these TVs is that basic functions like channel seeking or brightness controls now rely on a computer running Android. It feels like a 1000-fold increase in complexity and risk for something to hobble the TV part of the TV. Say the CPU overheats due to poor heat design after 3 years--it doesn't seem like manufacturers have a dumb mode to fall back on. Similarly, I'd be very worried if a car's radio prevented the car from driving.
It is sad that wanting a simple, modular display that we can upgrade peripherals around is niche these days. In a way, car makers took a step in the right direction with more radios adopting CarPlay & Android Auto, acknowledging that their own radios can't outsmart an evolving mobile ecosystem.
