I'd say it's worse--remember, the Library of Alexandria actually got partially (and usually accidentally) burned down several times throughout antiquity, and by the time it was destroyed on the Pope's orders, it was largely in ruins already. The destruction of Mayan codices was purposeful and malicious, and happened all at once at the hands of Christian fanatics out to destroy civilization--in other words, it actually was the kind of crime against humanity that popular history imagines the burning of the Museion was.
