Netflix is testing a more expensive abonnementssoort: Ultra. Interestingly enough, seem to understand current Premium members of the dupe to be, because those functions are going to return where they have become accustomed to.
About that write different websites, including Tweakers. Current Premium users now pay for 13,99 euros per month and can use it on four devices at the same time stream, with support for 4K and HDR. That option moves to the Ultra subscription, which 16,99 per month costs.
Premium members can still but on two devices at the same time stream and lose also the HDR function. Yet this seems only to apply to new subscribers and not existing. Also, it is not yet sure whether Netflix plans to permanently continue, at the end of last year, the streaming service also had a price increase.
