Setting the Text of a NotifyIcon: Can it make the icon flicker if done often with same text?

Question

My program does every few seconds:

icon.Text = message;

Often with the same message.

QUESTION: Does it make sense to only do it when message is different from last time?
In other words, can the code below ever prevent some flickering, or is it certified 100% useless?

if ( ! message.Equals(icon.Text))
{
    icon.Text = message;
}

No, it is not necessary, and actually wastes time for nothing, as the .NET implementation (at least version 4.6.1) does that internally:

    public string Text {
        [...]
        set {
            [...]
            if ([...] && !value.Equals(this.text)) {
                [...]
                this.text = value;
                [...]
            }
        }
