The LG G2 vs C2 vs B2 vs A2 differences are down to the following factors:

1. Do they have a heat sink or not? (Only the LG G2 has.) 
2. Do they have WBE or WBC panel? (The LG G2 and C2 have WBE panels (in the 55-inch class and above) while the LG B2 and A2 have WBC panels.)
3. Do they use α9 (Gen 5) or α7 (Gen. 5) processor? (The LG G2 and C2 use α9 (Gen 5) whereas the LG B2 and A2 use α7 (Gen 5).) 
4. Is the refresh rate 120Hz or 60Hz? (The refresh rate is 120Hz on the LG G2, C2, and B2, whereas the LG A2 has 60Hz refresh rate.)
5. Are their HDMI ports version 2.1 or 2.0? (The LG G2 and C2 only have HDMI 2.1 ports, the LG A2 only has HDMI 2.0 inputs, and the LG B2 has both HDMI 2.0 and 2.1 ports.)

LG B2 vs B1 (OLED77B2PUA vs OLED77B1PUA; OLED65B2PUA vs OLED65B1PUA; OLED55B2PUA vs OLED55B1PUA)

The LG B2 and B1 don't differ in terms of picture quality since they have identical OLED panels. The LG B2, however, has a newer generation image processor so it's has some advantages over the B1 when it comes to AI picture enhancements, as well as virtual surround sound upmixing.

LG G2 vs G1 (OLED77G2PUA vs OLED77G1PUA; OLED65G2PUA vs OLED65G1PUA; OLED55G2PUA vs OLED55G1PUA)

The advancements on the LG G2 vs G1 are mainly in terms of panel technology and processing power. The LG G2 utilizes the latest generation OLED Evo panel coupled with a heatsink, whereas the G1 lacks the heatsink and uses a previous generation of OLED Evo panel.

LG C2 vs C1 (OLED83C2PUA vs OLED83C1PUA; OLED77C2PUA vs OLED77C1PUB; OLED65C2PUA vs OLED65C1PUB; OLED55C2PUA vs OLED55C1PUB; OLED48C2PUA vs OLED48C1PUB)

The LG C2 vs C1 differences are mainly due to OLED panel improvements resulting in the LG C2 being able to get up to 20% brighter than C1 on full-field white, although this only applies to the C2 models in the 55-inch class and above as the two smaller models lack the Brightness Booster technology.

Samsung QN85B vs QN85A (QN85QN85BAFXZA vs QN85QN85AAFXZA; QN75QN85BAFXZA vs QN75QN85AAFXZA; QN65QN85BAFXZA vs QN65QN85AAFXZA)

The Samsung QN85B vs QN85A differences fall into the following categories: the first being upgrades (such as the 14-bit processing on the QN85B vs 12-bit on the QN85A; the QN85B's ability to diffuse light from the Mini LEDs in a way that matches shapes and surfaces being shown on the screen; the addition of a Dolby Atmos decoder).

Samsung QN90B vs QN90A (QN85QN90BAFXZA vs QN85QN90AAFXZA; QN75QN90BAFXZA vs QN75QN90AAFXZA; QN65QN90BAFXZA vs QN65QN90AAFXZA)

The main upgrades on the Samsung QN90B vs QN90A are the improved video processing, and the inclusion of a Dolby Atmos decoder.

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).
