This is a bit different than MTBF like on harddrives. Batteries are usually warrantied to 80% capacity because it’s a wear thing, not a random chance of complete failure. A battery isn’t going to last twice as long as another one by chance, this is all about determining the average or worst-case operating range the battery will be in and using that to figure out a warranty period where they think all cars will fall within.
These don’t seem to be particularly new panels. $600 and only 97% of the sRGB color space (= ~78% DCI-P3), meanwhile a similarly priced LG “QNED” can do 90-95% of DCI-P3. I’m not sure you can even call those TVs HDR if they’re only 8-bit color. None of these models can even remotely compare to a brand new OLED TV.
