combining all edge-cases together from above:

    ToString,

    Equals
}

public static class EnumHelpers
{
    public static string GetDisplayName(this Enum enumValue)
    {
        var enumType = enumValue.GetType();

        return enumType
                .GetMember(enumValue.ToString())
                .Where(x => x.MemberType == MemberTypes.Field && ((FieldInfo)x).FieldType == enumType)
                .First()
                .GetCustomAttribute()?.Name ?? enumValue.ToString();
    }
}

void Main()
{
    Assert.Equals("What a weird name!", Enum.ToString.GetDisplayName());
    Assert.Equals("Equals", Enum.Equals.GetDisplayName());
}
