Widevine L1 / Netflix 15001 error

Good morning!

Tomorrow I will unlock my Mi 9 bootloader and I was thinking about flash Xiaomi.eu like in my older Xiaomi devices. Knowing Xiaomi.eu is based in Chinese releases I assume it has Widevine L3, like chinese rom. Is this right? What Widevine level does Xiaomi.eu have? If it has L3, is there any plans about implement L1 in Xiaomi.eu?

Thanks you in advantage.
