Lakmé

Hello! I’m pretty new to opera, so forgive me if this is a foolish question. I listen to multiple different opera radio stations in the car, and as a newbie I don’t recognize most songs except the most famous arias. I heard the “flower song” from Delibes’s Lakmé, and although I couldn’t name it I recognized the music, as I did for the “bell song” from the same opera. I love these pieces of music, and I was shocked to learn the Metropolitan Opera hasn’t performed this since the 1930’s‽ (maybe I’m mistaken). It was hard for me to find any recent documented performances. Can anyone shed light on why this opera which has some powerful pieces isn’t performed more often? Is there something about the portrayal of Indians that doesn’t translate well in today’s world? Thanks!
