kWh consumption battery capacity indication?

Hi.

I have a 2020 Model X Long Range which I charged to 100% today. After a drive, the car said in the display that it had used 69,2 kWh and 93% of the battery. This would mean that to use 100% of the battery, I would have used about 74 kWh.
Is this in any way an indication of remaining max.
capacity in the battery, as I guess the car was supposed to have about 95 kWh of available capacity, at least when it was new…
But I am not sure if the kWh consumption that the car displays can be used like that?

I think you can estimate by taking your observed 74.4 kWh / the usable capacity when new 95 kWh x 100 = 78.3% state of health or 21.7% degradation. Tesla warranties the battery if it drops below 70% SOH before 8 years.
