As a contributing factor, rwy 06 in LUX has a pretty nasty upslope untill middle of the runway.
on the video it may look like a normal flare and nose position for the landing but that runway is comming up faster then usual.
From my experience landing on rwy 06 ,once the Radio altimeter start ls counting down from 30 feet onwards you have to flare as if you want to cause a tailstrike to have a normal touchdown 🫣
