It did not while we were there. Like the PP mentioned, they timed the opening with the small world clock so it seemed pretty exact to me.
Another difference is that on Monday, Tuesday, Thursday and Satuday Toon Town does in fact open one hour early but only if you have a Toontown Morning Madness Voucher included with Disney Resort Packages.
Also, if I recall correctly, WDW started the practice of opening early after Pixie Hollow opened and the crowds began lining up for Toon Town at opening. At DL, Pixie Hollow and the princesses have meet and greets outside of Toon Town.
