I thought it'd be interesting to compare the new 5.1 mix of "Let It Be" with the prior multichannel version from the 1/1+ Blu-Ray set. It's hard to believe these were mixed by the same team!
The new mix has Paul's lead vocal and the guitar solo isolated in the center speaker (with some support in the front channels as well), whereas the older mix barely uses it at all. I tried soloing the center and it sounds like a low-level mono summation of the front channels, like on those old Miller Nevada DTS-CD's that used transfers of '70s quad mixes.
On the 2021 remix, the rear speakers are deployed for isolated choir, brass, keyboard, and organ. If you mute the rears, all of those elements disappear. There's a particularly cool moment at 1:45 where the keyboard in the left rear channel is answered by the church organ in the right rear channel. The 1/1+ mix also features isolated choir and brass in the rears, but both elements can be heard at slightly lower level in the front channels.

As with Abbey Road, one of the coolest aspects of the new 5.1 mix for me is being able to hear Billy Preston's contributions isolated in the rear speakers. The electric piano part throughout "Get Back" in particular really stands out in a way I hadn't noticed before. Great work by Giles & Sam!
