Right next to it on the list
A rank or two either side of the Miele KFNF 9959 iDE: Miele KFMC 3846 R ($109/yr, 580 kWh/yr), then Thermador T36BB110SS ($109/yr, 580 kWh/yr).
Within the Miele lineup

Cost over its typical lifespan

Weighing a replacement
The Miele KFNF 9959 iDE runs above its category average. If the refrigerator you actually own is older still, likely well past ENERGY STAR's efficiency baseline when it was made, a current certified model could cost meaningfully less than this model's $109/year every year.
Worth comparing a few current certified models before deciding.
If you're keeping it
Whether or not the Miele KFNF 9959 iDE ever needs replacing, a repair is the more common failure for a refrigerator, one a protection plan budgets for ahead of time.
