In Settings, it will still say Mobile BRAVIA Engine 2 or Mobile BRAVIA Engine (Depending on your settings.apk) but that's just the renaming, the files I took from was in Xperia i1 Honami which also has X-Reality engine. ( i will soon port i1 Settings.apk which will fix this and you will also be able to pick between Nothing/Mobile Bravia Engine 2/X-Reality )
If you look carefully upon opening a picture in Albums, you will see that the picture will slowly enhance itself because X-Reality processes image in Real-Time so you can see what and how it enhances your image
