I think what she means is that Surbhi is basically carrying a role. And she's doing it as is.
If she is said to not emote well, then surely other actresses is just as. Nazia the character has so much potential, but is seen to be monotonous. And while Shazia has a lil more angst in her and has improved from the first scene, she still has potential to exploit.
And then there's Tanveer, even Amrapalli was said to give over the top expressions...but that is just Tanveer. So judging by that, I'm very sure it's just the character Sanam. She's not as lively and expressive as Zoya, she's more reserved and focused, keeps herself grounded (except with a certain Jaladh jin) yet there's this underlying charm, a current like state that is shown briefly at times and is yet to be discovered. And who but Aahil shall be the one to see it first.
