No, only 20 cars that were refurbished in 2019 (all apart of series 6) got all new seating. Every other coach that has been refurbished since the green branding was introduced just had the older seat style with the new colour. Series 1 was refurbished 4 years before series 6.
Also keep in mind, seats aren’t reused, they may visually appear to be the same as the older seats, but they are brand new seats.
This is such a minor detail to point out but the cushion is flat on the older blue seats, and shaped on the newer green seats:
