The EMT website says:
"We’ve improved our First Class dining, with extra service staff on board to serve you our range of complimentary hot and cold drinks (now with fresh milk) and our delicious at-seat menu (where available). A free breakfast snack is also now provided for Business Anytime ticket holders. A full breakfast menu is also available on selected morning trains to London....
....Throughout your journey, whether or not you require a meal, on weekdays every First Class passenger can look forward to free orange juice, ethically traded premium tea and coffee, still and sparkling water and savoury snacks, and wine on evening departures . On weekends we offer tea and coffee at your seat. And don’t forget, we also offer a fully licensed trolley serving wines, beers, spirits and soft drinks."
To think that under MML it was free tea and coffee for standard class passengers at any time, I wouldn't say they were improving anything!
