Wainwright won the first of his 64 Wales caps in 2018 and was part of the 2019 Grand Slam-winning squad.
However, the 29-year-old Dragons back-rower has also endured a miserable three years with Wales since his second World Cup campaign in 2023, with just two victories over Japan to show for the past 25 Tests.
Wales have conceded 50 points on more than five occasions in less than a year at the Principality Stadium – with Argentina, South Africa, England and now France all racking up record wins in Cardiff.
Their opening two games of the current campaign have also seen them ship 102 points, the worst defensive display of any Six Nations side in a quarter of a century.
“You don’t get better by not playing the best teams in the world,” added Wainwright.
“England were on a massive win streak, France one of the best teams in the world.”
Despite conceding eight tries against the defending champions, Wainwright insisted there were improvements against the French.
“I think we were quite tight in defence at times, a couple of times they were going passes off 10 or off nine quite wide and they were getting around us, so I think we just weren’t fanning out enough in [defence],” he said.
“I think they caught us there and once they get that, being able to go into their offloading there, it’s quite hard to get it back under control… that’s when they come into their own, so it was tough to deal with.
“So obviously looking forward to taking those learnings into next week.”
