I get the whole 'Katy doesn't take herself too seriously' but the way she has developed this theme just doesn't fit the song. It worked for CG, LFN and Roar 'cause the songs are ACTUALLY playful, campy and bright. I think she should've gone for a luxurious route, the possibilities are endless. Who cares if a mature/dark/ whatever video would've not gotten her massive amount of views, but at least it would've made a great companion + complement to the song.
This was supposed to be the E.T of PRISM
Also, I asked the insider if the grill or whatever the **** that is was too predominant in the video and she said Katy wears it for 15 seconds in a 45 clip she saw.

She told me she thought that If the grill appears a lot more than that in the rest of the video then she thinks the video will be ruined.
