There are different considerations: do you have 30Mbit/s upload or download? do you have hardware acceleration available to make a smaller/better encoding? is it actually used by your app? Otherwise, your app may restrict encoding quality settings so that it can run on many more devices (maybe that's configurable).

Also to consider: where does the connection flow through? if you're both going through Google/Amazon servers (SFU, etc), it's quite possible your ISP will provide a route with a decent bandwidth. It's also quite possible if you establish a direct P2P link or through a route your ISP considers less important, they'll slow it down or simply oversubscribe this route.
