Question Widevine L3 to L1 ?

[phobiahz]

Hi, I bought a chinese version of the Vivo x60 Pro +, some aspects of the phone appeal to me (like camera) but I am still disappointed in others.
Indeed, I discovered that the phone was not certified "Widevine L1" and my video on Amazon Prime & Netflix apps are ugly.
Is there a solution to obtain L1 certification or I should I think to migrate to another brand...
