Yes - but if you could extract (for example) some HDMI-like master keys (so you can pirate first run movies for resale), or eventual access to someone's billion dollar bitcoin stash, it might be worth the trouble. It's not something you'd do to get cheap netflix/etc It is something a government might do to get someone's crypto keys or iPhone, or to hack into foreign network infrastructure (Huawei/etc) (after all in the past they've built special purpose submarines to do such things)
