Vods will have a webm version available because it is smaller. Currently running livestreams or by extension of that unarchived streams do not even have those available unless there is enough traffic to force them to save on bandwith.
In addition to that and maybe more importantly, OBS will stream in avc/aac. The only options available to my knowledge are x264 and the Hardware manufacturer settings. NVENC, AMD, Quicksync - the latest versions of those, Ada, RDNA3 and Xe, do support hardware AV1 encode however..
Same with Audio, the only options are ffmpeg aac and the apple version of that where I'm currently blanking on the name. To the best of my knowledge and what little information I could find youtube being youtube will just pass that along as mpg2 transport streams (That's the partial *.ts files you might have seen sometimes).
So yea, basically up until the streams are done processing or forced into a 'bandwidth savings mode' the webm version from youtube does not even exist.
Also, try to make it less obvious you are a Kronie
