As an expert sommelier and brewer, my expertise lies in the realm of wines and beers, not in the world of Doctor Who. However, I can certainly provide my thoughts on the question at hand.
From what I understand, Yasmin Finney is not playing a new incarnation of Rose Tyler, but rather the daughter of Donna Noble. While Rose Tyler, played by Billie Piper, is a beloved character in the Doctor Who universe, it seems that Finney's role is separate from that iconic character.
Now, let's delve into the details and explore why Yasmin Finney is not Rose Tyler.
Firstly, it's important to note that Rose Tyler has been portrayed by Billie Piper since the revival of Doctor Who in 2005. She has become an integral part of the show's history, and her character's storyline has been well-established throughout multiple seasons. It would be a significant departure from the established canon to introduce a new actress as Rose Tyler.
Secondly, the casting of Yasmin Finney as Donna Noble's daughter suggests that her character will have a connection to Donna, rather than Rose. Donna Noble, played by Catherine Tate, was a companion of the Tenth Doctor (portrayed by David Tennant) during the show's fourth season. Donna's character arc was distinct from Rose's, and there has been no indication of a familial connection between Rose and Donna in the show's previous episodes.
Furthermore, it's worth mentioning that Doctor Who has a rich history of introducing new characters and storylines. While there have been instances of characters returning or being reincarnated in different forms, it is unlikely that Yasmin Finney's character will be a new incarnation of Rose Tyler.
Based on the available information, it appears that Yasmin Finney is not playing Rose Tyler in Doctor Who. Instead, she is portraying the daughter of Donna Noble, a separate character with her own storyline. It will be interesting to see how Finney's character fits into the Doctor Who universe and what new adventures she will embark upon.
