No, because it is a game, and not a documentary (see the fantasy sequences if in doubt. I can say, without fear of contradiction, many of those bear no resemblance to any known Beatles performance!).  

It’s quite okay for a fantasy sequence to feel like a weightless fantasy sequence; in a real-world sequence you need to be able to smell the sawdust. (Especially when you set out to contrast real-world and fantasy sequences.) It’s more about verisimilitude than accuracy. The reason that a big deal has been made about Disney-era Star Wars going back to “practical effects” after the CGI-heavy prequel films is because a Millennium Falcon model put together by an SFX crew from bits of found junk looks like a real ship, or like something that could be real, while it’s much harder to make something conjured out of the void in CGI similarly convincing. In the case of Rock Band Beatles, they modelled the real environments, instruments and so on, but without another living soul visible in the “studio” it’s still a bit too much like watching four breakfast-cereal mascots standing in an empty room.

(For that matter, it’s not as if a bit more of a nod to accuracy would have had no value as an end in itself either: George Martin, Yoko and Eric Clapton, in particular, are far from unknown to the general public. Then there’s the specific issue that airbrushing out Preston reverses a decades-long policy of acknowledging and highlighting his contributions.)
