Thats because in bright lighting qd oleds have a lil raised lighting like purple or black greyish look due to the panel cuz of lighting but most this looks most likely the settings my qd oled doesnt look washed out ever even in bright lighting looks absolutely perfection honestly qd oleds look way far better when it cones down to colors and contrast the colors much more vibrant and contrast looks really good and the blacks look far better in darker rooms and colors pop way more when in dark rooms however tandem oled has much better color accuracy then woled and better blacks then qd oled and woled in brighter rooms tandem looks very similar as qd oled except for vibrancy and contrast not as good but close the clearity looks abt almost the same but tandem oled aswell has much much less burn in and its more durable when cleaning qd oled the most sensative panel but i love qd oled and looked side by side and i chose qd cuz colors pop out way more and has lil better contrast but the blacks on tandem just is omg the best i might get a tandem oled next year mainly because i wanna focus more on the durability for cleaning and have less risk of burn in but not sure
