How to display different set of picklist values different accounts?

Now, In apex, we return a list of String which has all the values of picklist-

class PicklistValue {
    @AuraEnabled
    public static List<String> fetchPicklistValue() {
        Set<String> values = new Set<String>();
        for(Account acc : [SELECT valueField__c FROM Account WHERE valueField__c != NULL]) {
            values.add(acc.valueField__c);
        }
    }
    return(new List<String>{values});
}
