I flew TATL PV last weekend and can confirm that while the entree is Y, the appetizer and desserts are different. You get a real pillow and blanket, btl water and amenity kit (half contents of Affaires). The seat surface articulates/slides cradle like (two buttons, just up and down) with good leg raise and footrest. Reports are true that its thin/uncomfortable at shoulder level. No lounge access unless Elite+.
I understand that inter-Europe the food is the same as business, just no free middle seat. Within France (I flew W last week) all seats/service is the same onboard.
