3D was just something that was shoved down people's throats too soon. 1080p screens with active glasses were flickery messes that were also clunky and expensive. 1080p screens with passive 1080i 3D were simpler, but had poor quality. Combine that with the emergence of acceptable VR (3D with head tracking) goggles, a new 4K 3D format had no chance.
Now don't even get me started with "curved" screens... something that had no advantages for a TV, a display with multiple viewers sitting at relatively close distances to the screen, that was rammed down consumers' collective throats right after 3D.
