It doesn't. The only other time Sith spirits are mentioned outside of the Emperor's own and Momin's is a vague reference to Sith spirits/illusions conjured by Force priestesses on Moraband:
I, being a mere mortal, will not have my copy until Tuesday.
That being said, does the book allude to when Palpatine wrote it? Like, did he write the entire thing during his time in solitude on Exegol, or is it presumed that it was more of a journalistic text that was written at various points throughout his life?
I ask, because the section you posted certainly implies that he hadn't yet acquired the power/essences of all the Sith at the time he wrote that particular passage.

That’s disappointing, I was hoping it would explain that. He figured out how to do it somehow:
“He raised his perfect, healed hands, and called on all the dark power of the force and the Sith who had come before him, and pulled their very life from their bodies.”
-TROS Novelization pg. 284
I think the Star Wars databank confirms it as well, saying that he was a vessel for the power of all the Sith.
Palpatine evidently had not yet acquired the power/essences of all the Sith prior to the final confrontation with Rey and Ben, as according to that passage(which was apparently written during the events of RoS), there were still Sith spirits on Moraband that were calling to him.
That said, Rey was able to "insta-access" the power of all the Jedi in her time of need, by simply opening herself up to the Force... So I suppose a similar feat(albeit on the opposite side of the spectrum) might be in the realm of possibility for Palpatine as well. /shrug

I feel like there's more contradictions within SW now than there was in the past. They can't seem to keep things straight as new material gets released..
Nah, Legends had an abundance of contradictions also.
It's just that in Legends most of those contradictions didn't occur on the g-canon level, so they were easy enough to ignore or downgrade when they popped up.
But in new canon, all media is effectively g-canon. So when contradictions like this inevitably occur it creates more of a guessing game.
"Using Snoke as my proxy I reached into the boy's mind" - confirmation it was Sidious all along talking to Ben/Kylo.
In fact anything Snoke did could have actually been Palpatine.
Which means even IF Luke thought Snoke was Palpatine's equal, that could just be because he witnessed feats from Palpatine thinking that was all Snoke.
Kinda pissed that I bought it now, but here we are...
Palpatine was indeed using Snoke as a puppet/proxy to seduce Kylo to the dark side(we've known this for some time now), but Snoke's displays of raw power and such should have still been his own, as he was still a sentient/independent being.
Seems like Palpatine's influence over Snoke was more on the TP side of things.

Just confirms it, as the whole independent being could still apply to Snoke's TP communications with Kylo.
Yeah I mean there's the visibly obvious, like Lightning coming from Snoke's fingers, or Snoke raising his hand to choke Rey. That's obviously all Snoke.
Point being though, Palpatine was hiding his existence and acting via Snoke as a proxy. So for any huge displays of power where the source isn't so obvious or confirmed, but everyone just thinks/assume it was Snoke, there's literally no way to know what exactly was done by Snoke himself and what was done by Palpatine. And there's no reason to think Luke would know either. As he only suspected Palpatine was still alive, but didn't know for sure.
In fact maybe part of the reason he suspected Palpatine was still alive was because Snoke's power seemed so familiar to him.
If you have a chance could you post the rest of the page with the Dark Disciples on it? And if there’s any others as well, it looked like there were some gaps.

"And Kylo Ren is too torn between the dark and the light to pose a threat to my reign. The menace of the Skywalker bloodline is no longer a concern. Only the scavenger, Rey, exhibits the potential to prove my equal in the Force."
Sidious says Anakin’s power nearly rivaled his own:
“My power, both in the republic and in the dark side, would prove critical in bringing a young Jedi named Anakin Skywalker—a boy whose power nearly rivaled my own—under my thrall.”
Sidious considers Dooku’s most impressive disciple to be Ventress, which means he believes she is more impressive than Savage Oppress and Quinlan Vos since they are referenced later as his other disciples:
“Dooku’s first disciple (Ventress) was perhaps his most impressive”
