Only if the people that pirate the shows are able to obtain those higher quality downloads.
As these platforms become increasingly hostile to users, they're going to be well aware of the subsequent increase in piracy, and implement even more methods of preventing their content from being pirated.
It will always be impossible to stop piracy completely, but you can make it increasingly difficult to obtain best quality.
Keep in mind all of the various things that are starting to be implemented or suggested to ensure device/environment "integrity" in recent years. I promise a day is coming when Netflix and other streaming services will only allow streaming to "approved" browsers and devices, i.e. the ones that allow them to scrutinize every single bit of the stack down to the hardware.
