Details
From bug 1889717 we're collecting the timestamp that we report for LCP when we finish building the display list this doesn't match Chrome which is using the presentation time. This means our LCP times are artificially lower than Chrome's and makes it more difficult to compare.

It seems like this is more controversial than I originally thought. See https://github.com/web-platform-tests/interop/issues/215 which links to https://www.catchpoint.com/blog/why-first-contentful-paint-doesnt-work-as-a-cross-browser-metric
