enhanced version?


Oct 24, 2021
I'm totally new to Xiaomi and just received my phone this week. I've been reading lots of different things about updates and so on and at the beginning it's all very confusing to me.
My two questions:
1. I've got the 11 Ultra EU.version with RKACNXM.
is this already the enhanced version?
If not, is there already a stable ROM for xiaomi.eu for the enhanced version?

2. I wanted to install my first update (12.5.17).
Is it really necessary to do a data wipe before the first update?

Thank you in advance for your help! :)
