This is done by A/B Testing

HERE’S HOW A/B TESTING IS DONE AT NETFLIX

As soon as the test is live, they track specific metrics of importance.

For example, it could be elements like streaming hours and retention. Once the participants have provided enough meaningful conclusions, they move onto the efficacy of each test and define a winner out of the different variations.

Netflix later created a system that automatically grouped artwork that had different aspect ratios, crops, touch ups, localized title treatments but had the same background image. They replicated experiment on their other TV shows to track relative artwork performance. Here is an example:

The two marked images significantly outperformed all others.

Online and Offline performance evaluation is done with the help of algorithms and machine learning. Then the results are generated

There is also an even broader problem: helping artists and designers figure out what new imagery we should add to the set to make a title even more compelling and personalizable :)
