I have a NanoPC-T4 that I use as a server, the thing would in principle make a good set top box – it’s what Rockchip designed the RK3399 for, after all, it can decode 4k h.264 and h.265, and it’s from 2016 (I got it for its pcie lanes, a rarity with arm boards).
None of those SmartTVs run expensive hardware, any reasonably fresh potato can do what they do.
