Well, it depends . . . in a tune like "Invitation", I wouldn't necessarily regard Lydian b7 as the default, most inside choice.
But it's true that in modal contexts, each chord often tends to imply just one or two particular scales.
My main issue is with thinking that chords=scales, and the narrow and flawed thinking and hearing that that sometimes leads to with students. Not saying you think that, but just clarifying.
