LED is different than OLED. My 42" LG is about 10 years old.
It's also fair to say that a 10 year old LCD television with lousy integrated apps is not a proper comparison to their flagship technology and what would be their newest streaming tech. I have a 10 year old Roku and guess what? It's a piece of crap!
The streaming boxes are constantly going through revisions, getting better, and far more capable as time goes on. It literally costs you under $50 to make the old TV with a decent picture, but lousy 'smart' features into something that works perfectly by simply buying a Roku, Amazon Fire, or similar product. So, it's just not the way to judge any display on the market.
The ONLY way to judge a display is by the image quality it actually delivers and the price point for the display. Considering the price to image quality of the 55" and 65" C1 OLED displays, I find them a very hard price to pass up in a proper viewing area.
In a bright family room, the OLED models may still be too dim to be appropriate.
Seriously though... WHO CARES ABOUT SMART FEATURES? There are so many options. I wish reviewers would stop talking about them like they matter. There are YouTube reviewers who get this right, but so many get this wrong.
