The trial version of the Ultra tier also offers access for up to four devices at once, and in some regions that has pushed Premium down to just two.
This is because the changes may mean those paying for the £9.99 Premium tier would no longer be able to view on four screens at once with only Ultra subscribers getting that privilege.
Towards the end of previous year, Netflix raised its prices in the USA, with the most expensive option (Ultra HD, 4 screens) increasing from $11.99 to $13.99.
'It would be just great': Matuidi on playing with Cristiano Ronaldo
The "Jugones" report said Juventus would offer to make Ronaldo the highest-paid player in their history at €30m a year. France face Uruguay in a quarter-final in Nizhny Novgorod on Friday.
The Ultra plan, that is how Netflix calls it right now, is the most expensive plan up to date.
A basic account gets you standard definition and just the one screen at a time, while the standard £7.99 package gives you HD and doubles the screens.
Netflix users could soon have a new subscription plan to choose from. Pricing for the current plans are unchanged in this test, but the way the pricing is structured seems to be a way to disguise the price hike. It sure is, but Netflix is reportedly testing a new tier that is pricier than the current Premium tier.
Brazil vs. Mexico - Football Match Report
Neymar's dispute with Layun unfolded as the Mexico substitute tried to recover the ball. They caused problems for Brazil , too, initially.
A spokesperson from Netflix confirmed the tests to CNET, saying: "We continuously test new things at Netflix and these tests typically vary in length of time". For less than $14 a month, you can enjoy all the movies and TV shows you like, in Ultra HD, on up to four devices simultaneously.
The spokeswoman also clarified that the test is being conducted on a limited number of people, and not all Netflix subscribers will get the specific price points and features. The last time the streaming service increased its prices was last October, when the Standard and Premium plans were increased by $1 and $2, respectively.
While this makes things look disappointing, it should be noted that this is simply a test and Netflix says it's trying to "better understand how customers value Netflix".
