Why this matters for the Core Web Vitals, and where to start fixing it

Browsers start most images at low priority, because most images do not matter. The LCP image is the exception, and without help the browser only finds out after layout. fetchpriority=high says it upfront. A preload moves the discovery earlier as well. None means the most important resource on the page starts at the back of the queue.

One hint on one image. Spraying fetchpriority=high across the page puts the queue right back where it started.

How does this affect the Core Web Vitals?

The choice barely moves the LCP: 85% pass at best, 81% at worst. This signal does not separate passing sites from failing ones.
