Having watched the show (unlike you), I can categorically state that this doesn't reflect how her character is treated. At all.
I haven't seen the film, but the trailer for it barely hints at her Pakistani heritage, much less highlights it. On what possible basis, then, could people preemptively decide that her background is being made too much of?
It's clear you've formed a very definite notion of the character's ethnic and religious identity despite having literally zero firsthand knowledge of the material. I'll never understand it.
