Netflix or Netflix Premium?

I wanted to ask what the difference between the basic subscription of Netflix (7.99 euro / mon.) And the premium subscription (13.99 euro / mon.) Is.

Can look at more devices at the same time and if supported in 4k (with the most expensive package)

Premium allows you to stream only on 4 devices at the same time if you do not want to do that then you can also buy the basic package on the films and series does not change anything

4k and 4 devices at the same time
