Devtools: how to tell if asset is served from cache

I am using Chrome Canary dev-tools. Is there an easy way to tell if a particular asset has been served by a service worker from the cache (rather than from the server)? Network panel is not being very helpful

If the resource is loaded with a 304 (Not Modified) response, I typically consider that as being loaded with cache. Probably completely wrong way to look at it, but cache does get involved with that response code.

Otherwise, are you saying a normal shift-f5 “hard refresh” is not enough?
