Until you have a camera that detects watermarks and refuses to record. Its already there with cinavia which I guess has functional workarounds now, but it took, what 3-4 years (?) before a remover showed up that didn't garble the audio.
Its not at all hard to believe that in 20-30 years when all the non-drm'ed version are sitting in landfills the analog "hole" will be closed because capture or playback devices will simply refuse to function when they detect watermarks when interacting with unsecured channels.
I acted when ultra-hd was "cracked" and grabbed one of the friendly drives, but its not been particularly useful because there seems to be far less effort in the public to assure that ultrahd disks are readable (look up the details) so its more likely to "miss" these days. The point being that its a giant game of back and forth, and while the "crackers" win everytime they crack something, they are mostly hobbiest fighting against corps with billions to employ engineers who spend their entire day coming up with ways to make it more difficult. Given few of us have electron microscopes and giant supercomputers, it seems really likely they will eventually win given that they learn to compensate every time something is cracked.
Plus, in the past it was pretty easy to buy PC's/etc that gave you full control, these days even with secure boot disabled, you might not be able to get into the lower levels of firmware because the machine simply refuses to accept unsigned updates. Flash it by hand and the bootstrap code integrated on the CPU die refuses to accept it.
