Sony X80K vs X80J vs X85J (KD75X80K vs KD75X80J; KD65X80K vs KD65X80J; KD55X80K vs KD55X80J)

The Sony X80K vs X80J have a very few differences such as the ALLM (Auto Low Latency Mode) support on two of the X80K's HDMI ports, as well as the newer model being compatible with the BRAVIA CAM (which is an optional accessory). In terms of picture quality, the Sony X80K and X80J are nearly identical but the Sony X85J differs in that it has deeper black levels and better screen uniformity when displaying dark colors due to the VA panel in comparison to the X80K and X80J series (except for their 50-inch variants which also use VA panels). The IPS-type of panels ensure wider viewing angles and improved color reproduction on the X80K and X80J (except for the 50-inch class) when compared to the X85J, though.

Model Year 2022 2021
Size class 43"; 50"; 55"; 65"; 75" 43"; 50"; 55"; 65"; 75"; 85"
The Sony X80K, X80J and X85J come in identical sizes up to the 75-inch class where the X80K and X80J ranges end while the X85J goes further than than since it's also available in the 85-inch class.
Resolution 4K (3840x2160)
Display Type LCD
All three Sony TVs utilize a backlight because their pixels are not self-illuminating.
Panel Type IPS* VA
Except for the 50-inch class TVs from the X80K and X80J series which use VA (Vertical Alignment) type of panels. The precise IPS (In-Plane Switching) panel variant used in the rest of the two series is called ADS. It should also be said that there is a possibility of further differences between size variants, even within the same series, due to Sony not providing information about the exact panel they use in each size class.
Backlight Type Direct LED
Even though the LEDs are directly behind the screen, their arrangement is not full-array, meaning the Sony X80K, X80J and X85J are not able to perform local dimming and boosting of the backlight. Their direct LED backlight gives them an advantage in comparison to edge-lit TVs however, and it's in terms of the screen uniformity but that also depends on whether they use VA or IPS-type of panel since the former provides better uniformity than the latter.
Dimming type Frame Dimming
Unlike local dimming which can control the backlight in different area of the screen, the frame dimming that the Sony X80K, X80J and X85J are equipped with can only dim the entire backlight meaning not only shadows but also mid-tones and highlights are darkened. Furthermore, the three Sony TVs are not able to selectively boost the LEDs behind highlights, so the peak brightness in small highlights is identical to what they can achieve with high-APL content (where the screen is predominantly bright) such as hockey. While there isn't brightness fluctuation as the APL (Average Picture Level) changes, the highlights in HDR content also don't stand out.
Bit Depth 10-bit (Triluminos Pro)
The Sony X80K, X80J and X85J utilize 10-bit panels so the number of color shades they are capable of displaying is over a billion.
Anti Reflection No
The X-Anti Reflection technology that can be found on some of the Sony high-end TVs is omiited from the X80K, X80J and X85J.
Processor 4K HDR Processor X1
In addition to the same image processor, the three Sony TVs employ identical SoC which is MediaTek MT5895 which is in charge of running the Android TV system.
Refresh Rate 60Hz 120Hz
Thanks to the 120Hz native refrsh rate, the Sony X85J has a Motionflow XR 960 whereas the Sony X80K and X80J have Motionflow XR 240 due to their 60Hz native refresh rate which caps their motion interpolation capabilities to working only with up to 30fps sources while the Sony X85J is able to perform motion interpolation even with 60fps sources. Furthermore, the X85J is able to remove judder when playing 24fps content from 60fps sources whereas the X80K and X80J can't.
Gaming (exclusive features for PS5) Auto HDR Tone Mapping*; Auto Picture Mode*
Both of these features require a software update to be installed on the TV as well as the PS5 console before you can use them. Furthermore, the Auto HDR Tone Mapping has to be enabled during the initial setup, or you'll have to repeat this process (which entails disconnecting the TV and PS5, and performing factory reset). Due to the X80K and X80J having 60Hz native refresh rate, they don't support 120Hz signal but the X85J does due to having a 120Hz native refresh rate.
HDMI 2.1 features ALLM; eARC eARC 4K 120Hz; VRR*; ALLM; eARC
Even though the Sony X80J doesn't have any HDMI 2.1 ports, it's still has eARC (enhanced Audio Return Channel) functionality on one of its HDMI 2.0 inputs thanks to a dedicated chip. The X80K, on the other hand, is able to support ALLM (Auto Low Latency Mode) on two HDMI ports but due to the 60Hz native refresh rate it doesn't support 120Hz signal or VRR (Variable Refresh Rate). The X85J has all these features, except for VRR which will be added via future software update, according to Sony.
Sound X-Balanced Speakers
The Sony X80K, X80J and X85J have identical audio power output of 20 Watts delivered by two 10-Watt, full-range drivers.
Camera BRAVIA CAM (Optional) No
The BRAVIA CAM is sold separately. Unlike some of the higher-end Sony TVs, the X80K won't receive firmware update to enable the Ambient Optimization Pro intended to adjust the picture and sound automatically based on how far you're from the TV and what the ambient light is. Nevertheless, there are features such as Proximity Alert, Auto Power Saving Mode, and Gesture Control that the BRAVIA CAM can support when used with the X80K but these features will be enabled via future software update. The BRAVIA CAM can also be used for video without having to wait for a firmware update.
Stand Slim Blade Stand
The Sony X80K, X80J and X85J have identical table-top stand that can be mounted only in one way, so it's not possible to have raised and lowered position, for example. The 55-inch, 65-inch, and 75-inch class models are compatible with the ultra-slim wall mount bracket (SU-WL855) which is sold separately.
