The pre- touchdown retro fire certainly wasn’t as obvious as it is on most Soyuz landings…the commentator on the live feed referred to it as an air jet or air thruster system whereas other sources say it’s retro rockets (which is what Soyuz uses), be interesting to know what’s actually used.

FWIW the answer (as far as it goes) is tucked away on the Blue Origin website and was a phrase used pretty much verbatim by the official commentator on the day..

The bottom of the capsule has a retro-thrust system that expels a pillow of air so the capsule lands at just 1.6 km/h (1 mph) ”…

so unlike Soyuz it’s not a pyrotechnic system, which would explain the lack of flames, smoke, and relative lack of dust.
