Katrina doesn’t have a distinct accent because she moved around a lot, that’s the point. Had she lived in England longer she probably would have had a British accent like her siblings but she doesn’t, it’s mixed. Just like Priyanka, if she hadn’t gone to the US for high school or lived in the US for a decade after that and wasn’t trained by language coaches she would sound different too. Just like Katrina’s accent doesn’t sound 100% Indian neither does Priyanka’s American accent but both have been impacted by their experiences. Saying accents can’t change or adapt due to surroundings isn't true.
That’s the whole point. Her accent change isn’t a natural progression of time. She’s had speech and language coaches and worked on sounding American. People can debate on whether she was right or wrong to do so and whether it will help her career or not. But that still makes her inauthentic (putting it mildly) or fake and pretentious (putting it bluntly).
I’ve always read different stories of her time in America so I don’t even know how long she was or wasn’t here.
