Thanks for asking! The Picture: The S90C & S95C are both boosted by Quantum Dots to deliver over a billion shades of 100% Color Volume. The S95C steps up in Quantum HDR OLED+, providing you with further optimization to make bright whites and deep blacks crisp and clear. The Design: The S90C features our Laser Slim design with a super slim, sleek profile. With the S95C, you’ll see a nearly bezel-less screen with the Infinity One design. You’ll also gain an attachable Slim One Connect solution that neatly tucks cords and cables out of sight. The Sound: With Object Tracking Sound Lite, the S90C gives you 3D surround sound that follows the movement on screen using our virtual top channel audio. With Object Tracking Sound+, the S95C allows you to track on-screen action and project sound to follow the movement with pinpoint accuracy. Hope this helps!
