Not necessarily. A target change can alter the programme's drying endpoint or duration rather than simply increasing heat. The exact behaviour is model specific.
Understanding this situation
Do not infer temperature from the words extra dry, or use that target where the garment's drying restriction is unclear. Fabric selection and the care label remain separate constraints.
A useful next step
Read the model's programme description and select a supported combination. Report a changed finish with both fabric programme and dryness target. Touching the cabinet or a metal zip cannot establish the actual treatment temperature.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
