If you're already doing things like bundling any javascript, image sprites etc etc, you're probably not going to 'see' much benefit. Hence the tools aren't showing much difference. The big benefit you're going to see is if you are fetching multiple different files from the same domain. HTTP/1 would open and close a new connection for each request and had larger headers which were sent and received. HTTP/2 multiplexing allows a single TCP connection for all data from the same domain. I used it on a site which by necessity had to download (stream) 4-50 large files on many pages. With HTTP/2 multiplexing, we saw huge performance improvements, but that is a special case. It won't hurt you to use it, and I'm sure it is a good learning experience, but it isn't a necessity.
