IIRC, at multiple drops of Veritaserum, you volunteer information you think is relevant. So unless Lucius is holding the idiot ball, he should know all about the blood purity experiment stuff.
Of course, Draco was entangled with Harry from the start, so unless Lucius wants to Obliviate his entire Hogwarts career, basically setting him back a grade...
When canon!Hermione memory charmed her parents she didn’t have to take out all fifteen years of their lives that she’d spent with them. Likewise, when Mr. Hat and Cloak erased himself from Blaise’s mind he left in all the other stuff Blaise had done between talking to Mr. Hat and Cloak.
Memory charms can be selective. Lucius has time, money, and influence. He can afford to have a trustworthy expert go through Draco’s memory and edit out only the events that increased Harry’s influences over Draco in a fashion Lucius disapproved of.
“Assuming I survive our hunt for the Horcruxes, I’ll find Mum and Dad and lift the enchantment. If I don’t… well, I think I’ve cast a good enough charm to keep them safe and happy. Wendell and Monica Wilkins don’t know that they’ve got a daughter, you see.”
That doesn’t undermine my argument, though, since that’s canon and not EY’s version. Blaise remains proof that memory charms are selective and don’t just wipe out a whole patch of time.
(People don’t remember in a linear fashion, anyway.)

You read
as being selective?
I admit I never read it at all.
