Although they have very similar scores, PerfectRec considers LG G3 (OLED) to be excellent for news, talk, & other TV, while the Sony A90J (OLED) is very good.
The LG G3 is excellent for watching news, talk shows, and TV programs because it excels in upscaling content, which is crucial for watching lower-resolution broadcasts, and has very good SDR brightness, making it suitable for most lighting conditions. Whereas the Sony A90J is very good for the same content, due to slightly lesser SDR brightness compared to the LG G3, but it still offers high-quality upscaling and robust color performance right out of the box.
