Google is updated Google PageSpeed Insights tool to display partial field information. Google said “in the past, field information only appeared if all the information on the page or origin met the data limit.” “All data that meets the data limit is now provided,” Google said.
Google senior DevRel engineer Rick Viscomi said Twitter “In the past, you would see ‘no data’ if only FID data was missing. Now you see everything available. This is a big deal because ~ 30% of CrUX’s origin was missing from FID data!”
He also added these Tweets:
How does this affect the Core Web Vitals assessment? If FID is present, it must be good to enter. If the FID is missing, the page / origin is evaluated only based on its LCP and CLS.
The LCP and CLS must be present to evaluate the CWV.

This is reflected in the API’s loadingExperience and originLoadingExperience objects, as well as in the interface.
So now you can see a little more information when you may not have been able to see it before.
