The Sony X90K (LCD) is good for movies & TV, while the Samsung CU8000 (LCD) is poor.
The Sony X90K provides a better experience for movies and cinematic TV because it offers higher contrast and more effective local dimming, which results in deeper blacks and improved picture quality in dark scenes, key for cinematic content. In comparison, the Samsung CU8000 has lower contrast, no local dimming, and weaker black uniformity, which can cause grayer blacks and diminish the depth of images.

The Sony X90K (LCD) is good for sports, while the Samsung CU8000 (LCD) is only fair.

Al Griffin | December 2022
"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."
