Still 4-6 weeks of recovery, but that's mostly due to them having to inflate the abdominal cavity to be able to see / work and a bit of bruising and shifting of stuff.

As far as I can tell, gall bladder removal is a fairly routine procedure by now, and the risks and possible complications are well enough understood that a competent surgeon can tell after three days if the procedure went well or if there are any problems.

I Germany, hospitals usually get flat fee per case depending on the diagnosis, so there is an incentive to release patients as soon as possible. But all the doctors and nurses I have met so far take the health of their patients very seriously, and I do not believe they would release somebody who was still in need of medical care. Plus, ethical considerations aside, that might incur legal repercussions for the hospital and the doctor ordering the release, even in Germany.
Being able to get up and move around on the next day vs. having to lie in bed for weeks certainly makes a difference psychologically, but the laparoscopic procedure does put a much smaller burden on the body, too.
When my grandfather had his gall bladder removed (late 1960s, I think), he spent about 4-6 weeks in hospital and another couple of weeks at home recovering; last year, I had my gall bladder removed, they sent me home after three days. Now that's progress!
