Hello,
Using this command I can successfully capture a screenshot:
luna-send -n 1 -f 'luna://com.webos.service.capture/executeOneShot' '{"path":"/tmp/capture.png","method":"DISPLAY","format":"PNG"}'
But cannot actually start the grabber, no matter which backend I use:

Here is some diagnostic info as requested in the README:
root@lg-tv:~/hyperion# grep -h -E '"(hardware_id|core_os_release|product_id|webos_manufacturing_version|board_type)"' /var/run/nyx/*
"board_type": "O20_DVB",
"hardware_id": "HE_DTV_W21O_AFABATAA",
"product_id": "OLED65G1PTA",
"core_os_release": "6.2.0-33",
"webos_manufacturing_version": "03.21.10",
Any ideas as to why it's not working for me? I am trying to capture while using the HDMI input if that matters. I have tried using the hyperion-webos binary included in the latest piccap release, and also the latest binary from this repo.
Informatic commented
In practice only backend supported on 6.x is libvtcapture. The issue is that it requires proper Luna bus configuration, which we do not cover here in the readme. Easiest way of getting it set up is to install PicCap app from Homebrew Channel. webOS will properly set up luna bus permissions for hyperion-webos bundled with piccap (it'll be extracted into /media/developer/apps/usr/palm/service/org.webosbrew.piccap.service, and the actual final path of hyperion-webos executable is important there, in case you wanted to replace the release with some other version - there are some unmerged patches for libvtcapture in #43 / #40 PRs...)

Thank you @Informatic, I installed piccap using the latest release .pkg file, and got a little further with the libvtcapture backend, but still get some errors:

When I tried the libvt backend, I saw some corruption/artifacts on the screen, so hit Ctrl+C a few times to make it stop:

OK I got libvtcapture to work by specifically setting the capture width and height, which happens to be 480x270 in my case (a decimation factor of 8 for 2160p). Thank you for the help and this project!
I notice that libvtcapture is somewhat slow compared to the other two backends, according to the README. Is there any hope that those faster backends will work on 6.x in the future?
I have 'top' measuring about 65% CPU usage for the hyperion grabber, is this normal, or something I should be concerned about?
EDIT: There is also some noticeable latency, especially when compared to for example the grabber running on my Windows machine, would this be improved with a higher FPS capture? Both the TV and the hyperion server are connected to the network with ethernet.

I tried #43 and it did not noticeably change the amount of latency (although it seems to produce dumps of the buffer every few seconds, maybe that has some impact?). The latency I'm talking about is not a huge amount, maybe half a second or so if I had to guess. But I am coming from a Windows grabber operating over the same network, which has no noticeable lag at all.
Unfortunately I could not try #40 as the build artifact has expired and could not be downloaded.

Can you please checkout latest releases? It should work with them. If not feel free to reopen this issue.
