A response from Toyota may be iffy I would imagine. See they may just go by what the manual states which for the pre-facelift, states HB3. This is not the case though as it is the HIR modified HB3 that makes it a 9011 bulb.
If you want to see if it is a HIR bulb, you simply just have to look into the headlight housing from the front when you are in decent light (or using a torch), and see if the bulb looks like this... note the strange shape and slight tint around the middle of the bulb:
Otherwise, if you have a good camera, just take a close up photo of the bulb through the front of the headlight, or if you are willing, you can just take your bulb out and take a photo of it and I can tell you if it is a HB3 or 9011 HIR.
