Yes for diagnostics and CrUX when samples exist. No as a once-a-week screenshot that proves every client site is fine. Here is how agencies keep the two clocks honest.

A short board for agencies: Core Web Vitals by template, a few supporting diagnostics, deploy deltas, and tiered alerts. Leave the encyclopaedia off the default view.

One prompt can get a lab report into the green on launch day. It does not replace field data, a URL list, or a schedule after you connect the domain.
