i suggest you to try flashing the new roms and in case you get a blue screen , qfil latest firmware to update bootloader , i dont think theres another way to check the bootloader version .
And dont worry getting a blue screen wont brick the device or anything , if you get it just boot back to twrp and follow the procedure for updating the bootloader through qfil (there are plenty of instructions available ,read em carefully and you will be fine).
PS: you need an updated bootloader only for roms which ship with latest kernel 4.4 and not 3.18 .
so yeah you can try pie roms which have 3.18 kernel without hesitation.
Also keep in mind that if you do decide to update the bootloader and flash roms with latest kernel , you need to flash vendortofactory.zip and new factory twrp due to new implementation so DO READ THE INSTRUCTIONS CAREFULLY IN THE THREAD OF WHATEVER ROM YOU FLASH !
Mine is 3.18 kernal I guess I have to update my bootloader using qfil if want to flash pixel experience 9 pie
Can you send me the link for required files to update bootloader thanks ?

I've needed to update to ZUI 4.0 before installing Android 9.0 Pie ROMs.
Hi
Question.
I made my own 9.3.28 rom using OSDN script. https://github.com/XiaomiFirmwareUpdater/xiaomi-flashable-firmware-creator.py/releases
My Whyred has ARB 3 (Fastboot getvar anti). Since the beginning, i only flashed 8.1 firmware-less roms using TWRP.
I saw Whyred has Pie update. Will it mess my Whyred if i directly flash Pie firmware less rom ?
I did it on my Platina (Mi 8 Lite), and i had bootloop during 1st boot (crashing processus).
Platina is not affected by ARB. Then i took Fastboot Pie rom and flashed it, reinstalled latest Pie TWRP, magisk root, and everything's ok.
If i crash my Whyred with firmware-less Pie zip, i also need to reflash fastboot Pie rom, and kill my virgin ARB ?
So, it's impossible to update to Pie without destroying ARB 3 ?
So, i'm stuck on 8.1 ?
Use non arb FW update
There's pie beta firmware (9.3.28)
https://osdn.net/projects/xiaomifirmwareupdater/storage/non-arb/Developer/9.3.28/whyred/
Does using non-arb FW really works for updating from oreo to pie to maintain ARB 3?
because it didn't works for me (miui pie global stable with fwless rom & non-arb made using https://github.com/XiaomiFirmwareUpdater/xiaomi-flashable-firmware-creator.py/releases )
I experimenting on this but got bricked because unproper recovery installed.
If you want to experiment, make sure to install proper recovery and disable OTA survival.
Can be Downgrade Q to P?, Current version 11.012

I have done this by using MiFlash. (You will lose all data)
