Horrible softwares in TVs

I'd really want to get an OLED, but LG and Samsung both have insanely bad softwares. Like so bad that it has actually made me cancel my order for an LG OLED twice now.
My 2019 Samsung Q70 has a perfectly simple and working OS, not flooded with ads or unnecessary smart hub homescreens and what not. Just a simple home bar at the bottom of the screen, containing all of my inputs and apps that I use.

I'd go with Sony for the android, which is the lesser of the evils, but they are rarely in sale in here.

Right now I'm thinking of getting a TCL C9K, but I'm afraid I'd regret not getting an OLED.

Why do the TV OSs suck so badly?
