TCW Season 7's Validity in Legends

Hi there, are there any sources that can help confirm that the final season of the Clone Wars is not apart of the Legends Continuity?

I mean it wasn’t released during the time, that’s a big indicator. Not that it really matters since TCW was its own thing separate from the rest of the Canon.

The release date

It's not Legends because of its release date and there's nothing labelling it as Legends.

What everyone else said as well as the fact that TCW doesn't fit within Legends anyways.
