I would never expect to be made "more than whole" in situations like this, even though I have before - I just considered it a lucky bonus.So it sounds like followed the terms of the warranty, and put you back to where you were before the failure.
I just received my 2019 M3 sr+ back from Tesla after a failing HV pack displayed BMS code a066 for a few days, then eventually stopped charging. With Teslogic I could see a 30%+ degradation and a large cell voltage min max. Displayed max range was below 180 miles.

The dealership agreed it needed a new battery and I drove the car for a week until it would no longer charge. Dealership said the battery was ordered. My wife brought the car in for me when it would no longer charge and they gave us a 2019 M3 Dual motor as loaner.
Car was out of my hands less than a week before it was ready to pick up. The first thing I checked was Teslogic and the battery is definitely not new and actually quite heavily degraded. Quite disappointing to see such wear after a service like that. Anyone have a different experience?

Yes, 55.4kWh is not correct. There should be plenty of SMT read screen captures out there showing Full Pack When New value (which is about 52.5kWh).The Max capacity when new value of 55.4 kWh in your report seems to be off. I have the same vehicle (2019 M3 SR+) and the max capacity is 52.5 kWh according to @AlanSubie4Life. My battery capacity now is slightly less than your new one (45 kWh capacity instead of 45.5 kWh) and the degradation is 14.2%. Still not great, but not nearly as bad as the 20.8% reported by Teslogic. I also get the same rated range at 100% SoC (205 miles). So I don't think your battery has degraded nearly as much as you think.

Maybe the new pack is one from a newer vehicle and therefore higher original capacity then the battery it replaced?Yes, 55.4kWh is not correct. There should be plenty of SMT read screen captures out there showing Full Pack When New value (which is about 52.5kWh).
Not sure how Teslogic is coming up with this info, though. It seemed to get it right the first time with the old pack (52.4kWh). If it's reading this 55.4kWh from the pack, that's difficult to explain (however that value does not represent anything physical, it's just a value assigned to the pack that doesn't guarantee where the pack started).

However, in some cases, the warranty (or recall) replacement part was a better one, because the vehicle company chose to make an improved design that had a lower failure rate than one with a high failure rate, or because a newer variant in production that was better was a drop-in replacement for the old one.I saw this for years on the 2017-2019 Honda Ridgeline that had a 6-speed transmission with an unusually high failure rate. Owners would get remanufactured transmissions under warranty and get upset that they didn't get new ones.
It's as if some people expect to be compensated for their inconvenience by being given a product better than the one that failed. I guess I see the psychology in that, but that's not how warranties work

OP is very obviously using “dealership” colloquially to mean the Tesla service center.Dealer? Not Tesla direct?
I didnt assume. I just read the very 1st sentence of the thread.Why assume that, could have been used via Carmax and that is the dealer
What year, model ? Miles?
Only 13K km?2019 Oct / 13000km (10,000miles?), I charge it every Monday with Wall Charger (5A). Range suddenly dropped 40km. Reboot no help.
