The stat nerds say the same thing about Yadier Molina even though there's mountains of praise around baseball for his defensive impact. Anybody that followed baseball knows the Cardinals pitching staff had an obvious drop off in performance when prime years Molina was injured.
Even if you read the works of Bill James or listen to Brian Kenny, they make it clear that WAR isn't be all, end all of evaluation. You have to consider all information at hand. Simplifying it to WAR is lazy and not doing the homework.

Fangraphs also incorporated its own grading of framing and it absolutely hammered Perez's defensive value. I think their model overrates framing value, if for no other reason than it doesn't include metrics for other C defensive values.
I also think their methodology in grading framing runs saved is off somehow. They rate Perez below Sal Fasano in defensive value for their careers, which is as ludicrous as it gets and reminds one of what's been said about lies, damn lies, and statistics...
