Looks cool to me but maybe the security patch on Oreo is doing the trick. Try this, go back to the official Oreo 8.0 version and perform these steps again to root.

Yes, I followed the tutorial step by step?
Also did verified "OEM Unlock" : "Bootloader is already unlocked"
And at the boot time it is showing "recovery is not seandroid enforcing"
I tried the above procedure on "WARRANTY VOID: 0X1 (0X500) device, does this cause any issue.

If you see 'Recovery is is not Seandroid Enforcing' or 'Kernel is not Seandroid Enforcing', it probably means that you have installed a wrong CWM/TWRP recovery or wrong custom ROM on your phone or try to root the phone with a file that is incompatible with your current firmware.
So either your have rooted with the wrong root file or your phone's firmware version is not Oreo 8.0
