tried to run site with js and without. It looks same, nothing changes, so basically two identical images that starts at same time, and loads at same time in network devtools panel. But when js is enabled (it's heavy, yes, but has nothing to to with LCP element), LCP goes up +3 sec
Maybe defer the JS?
Well. I want to understand how does it affects this metric, because in theory, as I understand it now, it should not affect it at all
It definitely affects it
