Check what the mode changes and whether it suits the food being stored. An energy-saving label does not override the storage instructions on perishable food.
What the observation tells you
Models implement such features differently. A mode might adjust settings, display behaviour or other functions. It is therefore unsafe to borrow a temperature assumption from another appliance or treat the icon as proof that all contents remain appropriately chilled.
A useful next step
Read the manual, use a suitable thermometer where needed and follow official chilling guidance. If a new food-storage problem began after activating the feature, include that timing when requesting advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
