PageSpeed image issue

I’m using Cloudflare images, and on my home page, I have a 2.5kb image hosted on https imagedelivery dot net…

The image is 384 x 256 pixels and is 2.5kb, but pagespeed is telling me it is taking 2.7 seconds (Largest Contentful Paint element 2,700 ms). I thought Cloudflare images would give me faster speeds, esp for such a small image. Any ideas on what I can do?

I have all the optimisations turned on. Why would i be getting 2.7 seconds to get a 2.5kb image?

Any ideas are appreciated.
