Thai Airways earlier this year signed a lease for three 787-9s that will deliver in 2025, as their new batch of orders that were placed earlier this year will not arrive till 2027.

I wonder if those 787-9s are arriving a bit earlier and the configuration possible reflects the former operator of these three 787-9s. If they are fresh deliveries, maybe Thai is rolling out a new product!
Just a guess though!
