First off, glad to hear you enjoyed your stay here! Hopefully you'll return one day.
Regarding TF-FIW, it arrived from a lease with Yakutia Airlines just last month and as a result is still equipped with old seats and has, as you noticed, a different exit layout. Not sure if it will be changed or not. Unfortunately there isn't a seperate safety video for that one aircraft, but I'm surprised the FAs didn't mention the different layout in their welcome...
Anyways, hope you enjoyed your FI experience!
