Not berating you, just giving some friendly feedback for the sake of knowledge.
Well, a Saddleseat type horse's head/neck is usually capable of coming up high naturally. You have that high neck carriage, with a dropped nose, looking through the bridle, and whatnot. Ideally you are looking for a chess piece. If your SS horse's nose comes out, she is giving you the Royal F-you, evading the bit, telling you to go fly a kite... Not to mention that the first stages of training on a saddleseat horse, such as giving to the bridle, dropping their noses, coming down, is usually done in a snaffle. Double bridles are very advanced and come well after the single-rein to double rein on just the snaffle transition. In saddleseat, the bradoon or snaffle is used as your main control, and the curb used to set his head.
TBs are not highly sought after Saddleseat horses, even in the open classes, so I am skeptical of her former owner trying to make her so, as the natural high placed neck is not generally present on a TB. Not saying she wasn't but, even so, I am doubtful. Even in the open breed classes, you never see a person try to force a QHs neck up. If they are ridden Saddleseat, they should have their head where it is most comfortable for them, though still be collected and present a nice overall picture. I could not imagine trying to physically hold a horse's head in that position when they are not built to do so. That would require much arm strength and not be a very fun class. :)
As for your horse... what I see in the first video(haven't had time to watch the others yet) is not so much that her head is up, but her nose is out. Nose out in any picture to me says "I am fighting and/or not listening to this bit". It could be that she is used to being cued from the curb to drop her nose, and without it is evading.
