I use vp9 for my webm’s as well fwiw. The configuration of the host can also impact things. For instance, if I direct link to an image on twitter, their configuration blocks lemmy from showing a thumbnail or expanding the size. So, that is why I tend to post visuals from Comic Natalie (their CDN plays nice), or just upload the image directly.
It looks like webm (maybe because of vp9) doesn’t work on the photon via shota.nu either.
