Oh yes with respect to Avif you are correct. I was more referring to multimedia messages in general. But you are correct about Avif. That format in particular is not well supported a lot of places. I know Linux is probably one of the few areas it sees much. Windows is a much different story and I’m sure Apple desktops as well.
Apple only supports avif on paper and doesn’t actually support avif in iMessage in practice. It won’t display properly and they don’t care to fix it.
On the Android side Google Messages Doesn’t appear to support avif at all
