This incident is reminding me of a game I heard about that involved Babe Ruth when he was still a pitcher for the Red Sox. He’d been out partying the night before and had a fearful hangover. When the umpire called a walk on the first batter, Ruth took the opportunity to argue the call and got himself thrown out of the game. The relief pitcher (I think it was Addie Joss) throws out the runner trying to steal second and then put down the next 26 batters. For years, this game was counted as a perfect game. About 10 years ago, MLB got around to cleaning up the record book and decided that this was not a perfect game.
As far as this current game goes, I wouldn’t be too upset if the umpire was overruled.

Whether this was considered a perfect game or not, I don't know. But If it had been, it was corrected long before 10 years ago. When I listened to Larsen's World Series Perfecto back in '56, it was called baseball's first perfect game.....ever.
The current official Major League Baseball definition of a perfect game is largely a side effect of the decision made by the major leagues' Committee for Statistical Accuracy on September 4, 1991, to redefine a no-hitter as a game in which the pitcher or pitchers on one team throw a complete game of nine innings or more without surrendering a hit.[43] That decision removed a number of games that had long appeared in the record books: those lasting fewer than nine innings, and those in which a team went hitless in regulation but then got a hit in extra innings. The definition of perfect game was made to parallel this new definition of the no-hitter, in effect substituting "baserunner" for "hit". As a result of the 1991 redefinition, for instance, Harvey Haddix receives credit for neither a perfect game nor a no-hitter for the game described below in which he threw 12 perfect innings before allowing a baserunner in the 13th.[44]
