No. Different metals and decorative finishes can have different care requirements. Dishwasher suitability must be confirmed for the actual item, not inferred from its strength or appearance.
Understanding this situation
A polished surface may change even when food is removed. Plated or lacquered pieces add another layer of uncertainty, and a mild-looking programme does not guarantee protection.
A useful next step
Follow the maker's instructions and use the prescribed alternative if needed. If a finish changes, avoid abrasive experiments inside the dishwasher. Distinguish material damage from residue on otherwise dishwasher-safe items when describing the result.

Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
