One wonders what ATC told the crew about runway conditions. The a/c would have been light, I assume. Parcels weighting less than pax + baggage. What landing flap & autobrake did they use? Did they use TR's on a night arrival - noise abate? Where was the touchdown point? What was the Metar? I suspect, being dark, the touchdown point might not be assessable by ATC. However, the crew can answer the other questions.
