Lab LCP vs Field LCP Chrome UX Report

Lab 1.24 s
Field p75 1.96 s

The lab LCP is 0.63× the field p75 — real users likely have below-average hardware or network connectivity. A gap this wide usually means real users are on slower devices or networks than the simulated ones — the lab number is flattering you.

The same load, photographed twice at 412×823: once with scripts disabled, once as rendered.

Scripts disabled
As rendered

0.9% of pixels differ — they are nearly identical. A shifted layout counts as difference, so a <noscript> banner alone can account for a large figure.
