In the case of 1014116, the pack is a new configuration of 100kWh pack, as others have mentioned, with two modules removed, making it ~85kWh, 350VDC with the 90kWh chemistry (instead of the old 85kWh). I would say all 1014116 packs (A or B) are new at this time. The B just being the newer revision.
I believe the 1014116 pack being the replacement for the old 85kWh packs was reported first in Jan. 2020 with lots of good discussion in the thread below:
Got my original battery pack revision "B" (unsure of the part#) replaced over the weekend and just picked up my car. To my surprise, I now have a new battery showing a ~92% charge to be 265mi and according to the app, 100% is 288mi!!! I initially thought I got a 90kWH pack as a replacement...
