The screen has arrived, and everything is working great! (maybe except the touchscreen but still better than nothing).
I (luckily) got a screen that was similar to the original one that came with my device, with slightly higher VCON at -2.65 compared to the original at -2.32. That said, the plastic layer on the front seems much more glossy compared to the original; however, that can be easily remedied by using a matte screen protector (which I will get soon). Also the frontlight is 'yellower', but I don't mind that, since I prefer my display to look more 'paperlike'.
For those who also want to replace their own Kobo Aura screen, I'll leave the links below to a teardown video and the screen I bought off AliExpress.
Thanks to all who has chimed in, I'm now really happy after nearly one month without reading

. Now off to change my device flair...
P.S I used ePacket shipping method instead of AliExpress Standard Shipping, and item arrived in 12 days. Pretty fast I think.
