Here is one of the legacy A320neo that has been recently converted into a new configuration with the new livery, however VT-EXN, and seeming the other legacy Neo’s to follow, will be painted in a livery with notable differences to what we saw on likes of VT-RIO (missing mask around the cockpit, missing the annoying dark line on the tail, the flag placement, and the pattern work on the tail blended better rather than just abruptly ending at the elevator tab, and most notably the vista pattern on the tail has a design on it rather than it just being a solid colour).
I actually prefer the newer adaption of the livery, although I personally would’ve liked to see the mask. I hope the airline sends this template to the manufacturers now so that Air India can at least see uniformity in one place in their ever changing environment.
