The page you get when DOMContentLoaded is finished is a white page with no content. The page is only loaded in a very technical sense for sites like bbc.com.

Google page speed (https://pagespeed.web.dev/analysis/https-bbc-com/yxcpaqmphq?...) use two other terms. First Contentful Paint, that is the first point in the page load timeline where the user can see anything on the screen, and Largest Contentful Paint, the render time of the largest image, text block, or video visible in the viewport, relative to when the user first navigated to the page. For bbc.com, those sites around 1 second mark.

Other measuring aspect is Time to First Byte, which is the time between the request for a resource and when the first byte of a response begins to arrive. For bbc.com that is 300ms.
