At the time there is no direct was to do such things based on the documents
mime type.

I can't imagine how this could be achieved. Even if you set up :autocmd for
LoadFinished you don't have the mime type available.
But hey, you can try something like this.
Add autocmd to check the content of each loaded page
:autocmd LoadFinished * sh! ~/bin/runJsonPrettifier
Script that is feed with the page content to check if it's JSON
(runJsonPrettifier).
#!/usr/bin/env bash
cmd="<Esc>::e document.getElementsByTagName('body')[0].innerHTML<CR>"
content=$(echo "$cmd" | socat - UNIX-CONNECT:$VIMB_SOCKET)
if [[ "$content" = isJASON ]]; then
echo "<Esc>:e prettyPrintJSON($content);<CR>" | socat -
UNIX-CONNECT:$VIMB_SOCKET
fi
I'm not sure if this works. But it's a really overkill and not the direct way.
But maybe this is an inspiration to get your JSON pretty.
