The codename for the LG V20 is "elsa", but LG only provides bootloader unlocking support for the us996 variant (sold by US Cellular).

Display Cutout

Unlike most smartphones with display cutouts (aka "the notch"), the LG V20's touchscreen does not register input underneath it. Until there is better support for display cutouts, it may be a good idea to simply not use that row of the display. This could possibly be done by changing the screen dimensions, and panning. See this LineageOS commit disabling the section of the screen next to the cutout

Mainline Kernel

The SoC, msm8996, has support in the mainline kernel. Since this phone has a removable battery and a decent amount of ram & storage, this phone could be usable in the long-term, making it a prime candidate for mainlining.

Obstacles:

  • The display panel, made by LG, uses display stream compression, or DSC. While the mainline kernel does support DSC *for the sdm845 SoC*, it does not support it yet for the msm8996 (as of 12/28/2021). Additionally, the simple framebuffer approach cannot be used for display output, because the panel is command-mode - not video-mode, and the bootloader disables autorefresh.
