The Sony X90J (LCD) and Sony X90K (LCD) are both good for movies & TV.
The Sony X90J provides a slightly better contrast and more effective local dimming than the Sony X90K, which is why it stands out for movie watching and cinematic TV, delivering deep blacks and minimizing blooming around bright objects. However, the X90K offers slightly wider viewing angles and more uniform grays, making it a good choice as well if you're sitting off to the side or have a wide seating area, though with a small trade-off in black uniformity.

The Sony X90K (LCD) and Sony X90J (LCD) are both good for sports.
The Sony X90J is known for its excellent motion processing and response time which are crucial for sports; however, it is less effective at handling reflections, meaning it might not be ideal for very bright rooms. Meanwhile, the Sony X90K also delivers excellent motion processing and has very good response time, but offers slightly better performance in bright rooms due to its fair handling of reflections, though it has slightly lower gray uniformity which may affect the viewing experience when watching sports with large uniform colors like a football field.

Although they have very similar scores, PerfectRec considers Sony X90K (LCD) to be very good for bright room, while the Sony X90J (LCD) is good.
The Sony X90K performs better than the Sony X90J in bright rooms largely because it handles reflections better, maintaining a clearer picture when there's ambient light. Additionally, both TVs have very good SDR and HDR brightness, which is crucial for overcoming glare in well-lit environments, but the X90K's slightly superior HDR brightness further enhances its suitability for bright rooms compared to the X90J.

"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."
