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. There is a downgrade in the actual speaker system on the LG B2 vs B1, though, since the B2 omits the subwoofers that can be found on the B1.

Model Year 2022 2021
Size class 55"; 65"; 77"
The LG B2 and B1 come in the same three size variants.
Resolution 4K (3840x2160)
The resolution is 3840x2160 for all models in the B2 and B1 series.
Display Type OLED
The LG B2 and B1 have four subpixels (white, red, green, and blue) since they use W-OLED panels.
Panel Type WBC
The LG B2 doesn't have an Evo panel that can be found on some of the step-up LG OLED TV models. Instead, it uses WBC panel (just as its predecessor the B1), meaning there is no brightness improvement on the B2 vs B1, nor is there any increase in the efficiency or longevity of the organic light emitting diodes.
Heatsink No
In the absence of any extra brightness (and the heat buildup it may cause), the lack of a heatsink on both the LG B2 or B1 is understandable, and doesn't affect the picture quality in any way (apart from any temporary image retention taking slightly more time to clear up).
Viewing Angle Wide Viewing Angle
Given the identical OLED panels used by the LG B2 and B1, the viewing angles are also similar with both TVs being able to retain the image quality largely unchanged during off-axis viewing.
Dimming Pixel level Dimming
Even though the LG B2 and B1 don't use the latest generation of OLED panels, they can still achieve a perfect black level on a pixel level (due to their capability to turn individual pixels off and on) which also makes them impervious to image artifacts such as blooming or halos.
HDR formats HDR10, HLG, Dolby Vision
The LG B2 and B1 support the same HDR content formats.
HDR processing Dynamic Tone Mapping
Unlike some of the higher-end LG OLED TVs which can generate dynamic metadata by analyzing 5000 blocks of the frame when watching content with static metadata such as HDR10, the LG B2 and B1 perform Dynamic Tone Mapping by averaging the luminance levels for the entire image which may lead to some details in shadows and highlights being lost.
Dolby Vision IQ
The LG B2 and B1 are equipped with the standard Dolby Vision IQ technology (without Precision Detail), meaning that they can adjust Dolby Vision content according to the ambient lighting of the room (by using information from the TV light sensor), but are unable to improve the level of details in dark or bright areas of the image.
Color Billion Rich Colors, Wide Color Gamut; 100% Color Fidelity
There is no difference in the number of color shades the LG B2 and B1 are able to display since both TVs have 10-bit panels which translates to over a billion rich colors, as LG frames it. The LG B2 and B1 support wide color gamut in the form of the DCI-P3 color space used in HDR content. Both OLED TVs are certified for their 100% Color Fidelity because a test conducted by Intertek found the Delta-E (i.e. color difference) values were less than 2 for each of the 125 color patches, meaning these colors are perceptually almost indistinguishable from perfect, albeit a calibration may be needed to reach that level of color fidelity.
Processor α7 Gen 5 α7 Gen 4
In terms of image processing, the LG B2 is able to attain AI Picture Pro-level thanks to the Gen 5 Alpha 7 processor whereas the LG B1 has a standard (i.e. non pro) level of AI Picture due to Gen 4 Alpha 7 processor. The same goes for sound processing with the LG B2 having the AI Sound Pro while the B1 has the standard AI Sound. Owing to enhancement in the deep learning algorithms, the LG B2 is able to distinguish foreground from background elements, and enhance them accordingly so that the image appears more three-dimensional. Both TVs are able to perform AI Upscaling, though.
Virtual Surround 5.1.2-ch (up-mixed) 5.1-ch (up-mixed)
The LG B2 is able to create virtual height channels in addition to the surround channels from its stereo speakers while the LG B2 is limited to creating virtual surround sound only.
Audio 2.0-ch; 20 Watts 2.2-ch; 40 Watts
The LG B2 omits the subwoofers that can be found on the B1 which explains the lower audio power output on the B2 since the two LG OLED TVs allocate 10 Watts per channel to their speakers. The remaining 20 Watts on the LG B1 are for the subwoofers, which allow for considerably deeper bass in comparison to the LG B2.
While the support for cloud gaming is identical between the LG B2 and B1, it should be said that it's added via a firmware update on the B1 whereas it's out-of-the-box with the B2.
Input Lag ~13ms (@60Hz); ~6ms (@120Hz)
Both TVs are equally suitable for gaming due to their extremely low input lag.
VRR HDMI forum VRR; AMD FreeSync Premium; G-SYNC Compatible
In addition to supporting variable refresh rate as defined by the HDMI forum, the LG B2 and B1 are compatible with two other propriety solutions from AMD and NVIDIA in order to ensure that gaming is both stutter and tear-free.
Game Optimizer 5 Game Genres; Dark Room Mode 4 Game Genres
The LG B2 has one new game genre that you can select in the Game Optimizer menu: Sports. The remaining options (i.e. Standard, FPS, RPG, and RTS) are found on both TVs. The B2 also adds the Dark Room mode so the screen brightness is adjusted automatically when ambient light is low.
Smart TV webOS 22 webOS 6.0
Multiple user profiles are supported on the webOS 22, meaning that up to 10 people can have personalized content recommendations and app arrangement on the home screen. Another new feature is the Room to Room Share (although it will be added via a future firmware update to webOS 22). Once available, cable or satellite content can be mirrored from one TV to another via Wi-Fi.
Stand Centrally-mounted
The LG B2 and B1 have similar table-top stand that is centrally mounted.
