Chuwi Hipad X Widevine L1

according to Chuwi store, the Hipad X is Widevine L1 certified:

But in my tablet I can see only L3 compatibility.
What is the software version certified with Widevine L1??
Thanks and BR

Simply amazing, customer service from Chuwi is non existing at all. I have been asking for weeks in chat found in, which claims “we reply immediatly”, and nobody answered in 5-6 weeks. And here, nobody answered either. They advertise a product to be L1 compatible, which is not, and nobody from Chuwi is going to answer?
