Your claim, precisely as stated, appears to be true but, per your link, that doesn't mean that the watermarking hasn't been broken in other ways. In fact, citation 16 regarding DVD-Ranger CinEx appears to do precisely that: detect the signal and then remove it.
The Amazon technique sounds like exactly the same crap that you get from a lot of machine-learning researchers doing security work: they don't think about an adaptive adversary. There's an entire field of adversarial machine learning that works by training a machine-learning system on the inputs and outputs of another: if you can train a neural network to insert and recognise these watermarks, can you train another one to recognise and remove them? If you haven't even tried that, it's likely that an attacker will be able to.
