This is wet blown. There is a water nozzle that adds water to the cellulose and then a knife is run across the face of the studs and "planes" the surface. Stuff that ends on the ground is swept up and reused.
Dense pack has a fabric mesh that is glued to the face of the studs and then stapled on the edge to draw it as tight as possible. If you don't glue the face insulation can get between the face of the stud and mesh and cause issues with dry wall when its installed. A cut is made about head height and the blower hose shoved down in the cavity and as it fills up tight is slowly brought up until the hole is reached and then is shoved up and withdrawn down. The density is much higher which doesn't add R Value per se but increases resistance to air currents which raises the overall performance. I have done two buildings with dense pack if you have questions, both with mooney walls to add depth and reduce thermal bridging

Wet sprayed is pretty good however, nothing to sneeze. The big gotcha with wet spray is you really need to let it dry a few weeks depending on if AC or humidity before covering.
