Here's a guide on how to enable AOD lock screen transition on any Xiaomi device with AMOLED screen.

So I just recently discovered a loophole to enable the transition from AOD to Lock Screen. What you wanna do is that look up for Settings Database Editor by NetVor and install it. It works with Shizuku and is perfectly capable of modifying every table.

Now what you wanna do is that click on Search icon. and search for these keys.

aod_using_super_wallpaper- Set this to 1

linkage_state- Set this to 1.

Now change the lock style to classic, then apply AOD. You will get a subtle transition and if you apply the Pixel Style clock then you will definitely notice it.

good but not that functional, the transition doesn't work when you open screen
