Sorry to have nothing to contribute, but I'd like to bump up the plaintive wail for explanation, as I've always found LeafSpy confusing. The online LeafSpy manual claims that
The red bars represent those cell pairs that have the shunt active to bleed off some of the stored energy and balance the battery pack

, which seems to say that only the two very highest-voltage cells shown in the OP's histogram don't have their shunts on; wtf ??? So the rest of the cells will be pulled even farther out of balance?? If someone is able to give it, I would really like to hear an explanation of this counterintuitive coloring of the cell voltage histogram bars.

I'm wondering if this isn't a very active forum, or maybe I've posted in the wrong area?

Battery condition appears to be like new. Do you know the history of the car? I am guessing that it has been in a cool climate for its entire life or the LBC (lithium battery controller) has been reset by an unscrupulous dealer or repair shop. There is a setting in LEAF Spy for the shunt order. I am still not sure what the correct shunt order setting should be after using Leaf Spy Pro for 4-1/2 years on two different cars. The QC count of 2 indicates that the car has only had one quick charge after leaving the factory (1 charge during factory testing). The climate control and/or charge timer were likely used often to cause the L1/L2 charge count to be a little high for the odometer reading. Enjoy your new to you car.

April 1st was a couple of weeks ago.
I noticed you're still working with polymers.

The battery is either in like new condition or it was reset.
You will know in a month or two when you LeafSpy again

Or you can go for a r/t drive on the highway at ~ 100 kph without accessory use. A like new battery should be good for ~ 144 km unless the driving conditions are poor. You can use the change in SoC for shorter drives, but be sure to drive at least 50 miles total and end at your starting point.

I've been driving the car for almost a month now and I have put about 800 KM (500 miles) on it. since it was new to me, and I just took this screenshot yesterday. Most of my trips have only been down to about 50% battery, not sure if I've been on a really long range drive with it yet, I'll give that a try today and see if anything changes on the LeafSpy screen. I picked up the car used from a Nissan Dealer, but they don't know the history of the car either. So no idea if the battery was replaced at all during its previous life.

Increasingly high chance you have a like new battery :D

I suggested you take a long drive to correlate actual range to the LeafSpy result.

Well first off you want to know what the likely high water marks are

ahr; 67.20
GIDs 284 (GID =77.5 wh)

The rest are HIGHLY variable.

Is this a full charge? When you are this close to full, its important info to know.
2011 SL; 44,598 miles. 2013 S; 44,840 miles.2016 S30 deceased. 29,413 miles. 2018 S40; 11,987 miles, 485 GIDs, 37.6 kwh 110.89 Ahr , SOH 96.00, Hx 115.22
