If you had mentioned that quote why did you say Toriyama didn't say it ? I'm confused.
The quote that Toriyama didn't say was the one you posted before:
"aftermath of the buu fights, with peace on earth"
The part about "peace on Earth" makes it clear that you were thinking about the Toei press release. The later quote that you posted says nothing about that.
You have an author writing a story outline and general guideline, and you have a team fleshing out the ideas and writing TV episodes. They consult said author about their work, that either modifies or approves the work.
If Toriyama comments about the precise storyline of Dragon Ball Super, that means that he was fully aware of it, and it is part of what he wants, whether he wrote it specifically, or not. For instance, he did want Goku as a farmer, but he very likely did not write specific scenes for Goku farming.
I'm not saying that they're somehow doing the remakes of BoGs and RoF against his will, I'm saying that, at this point, we have no way to know if the changes that they're doing to those stories are part of Toriyama's outline or just ideas from the tv crew. Several ideas brought up in the show, like farmer Goku and Beerus being the one that sealed Supreme Kai in the Z Sword had already been mentioned by Toriyama in various interviews and Q&As. So, yes, some of them are certainly Toriyama's ideas, but you can't say for sure, at this point, that all the other changes are part of Toriyama's outline, especially considering the lack of commentary about them.
I mean, consider how they cut the scene where Videl's pregnancy was revealed in BoGs, only to shove it right before the SSJGod ritual, leaving Pillaf and crew basically without any role in the BoGs arc. There's also how the idea about Goku disliking powering up without his own effort was completely cut from the BoGs anime arc. Yes, there's a chance that those changes were suggested by Toriyama for some reason, but I don't think we can really say for sure at this point.
As for universe 6...
He is working as a writer and designer, what else could he possibly say when talking about a new story than "i've written a new part" ? We already knew he had created battle of gods and resurrection F, he had no reason to reaffirm it in the opening, that'd be rather obnoxious.
He could talk about why some elements of those arcs needed to be changed, but he said nothing, aside from saying that Super would cover them.
The anime is in no way going against his true vision. It might add stuff left and right to flesh out episodes, but it's not contradicting or changing the vibe of anything he wrote.
We saw what was his true vision, at least at the time, when he actually had input in the final product with BoGs, where he actually heavily changed the final script or wrote the initial script for RoF (which only had a few minor tweaks afterwards, even if it left some elements vague due to cutting the non-scripted scenes that the script described). Yes, he has a role in Super's planning, but when I see the anime using anime-original characters, or even outright replacing some elements from Toriyama with anime ones (like referencing the Bardock Special for child Vegeta, rather than Dragonball Minus), considering the lack of commentary about these changes, I hesitate to take it all as his "true vision".
