That specifying is not done by the adjective "delicious". If "delicious" is to be interpreted as narrowing, it would be something like "thank you for the delicious carrots; no-thanks for the yucky peas".
Other examples:
"The scariest thing about a rattlesnake is its deadly venom". (This sentence is not intended to contrast a rattlesnake's other, non-deadly venom, but rather emphasizes that its venom is categorically deadly).
"Our mortal bodies may die, but our immortal souls will live on". (Implies that all bodies are mortal, and all souls immortal; not specifying the subset of bodies that happen to be mortal).
"I'll place my trust in solid steel over empty words". (Implies that the speaker believes words are always empty, and only actions matter).
"Consider the humble pencil". (Implies that a pencil is humble by its nature, not a specific pencil that is humbler than others).
There's no clear rule, but generally, if the adjective describes a property of the noun that is already understood to be intrinsic to that noun, then it is more likely to be interpreted as emphasis rather than as a modifier. (Deadly venom, delicious food, solid steel, immortal soul). "Toxic masculinity" is in a sort of Schrodinger-state, where it can kind of go either way depending on contextual clues, basically, the reader's perception of the speaker's beliefs about masculinity itself. And once you've chosen a reading, even subconsciously, that will reinforce your preconception of what the speaker meant by their grammar. Like the blue-yellow dress illusion, people will read it one way or the other and not understand why others disagree.
So if I say something like "the problem with fraternities is that they are awash in toxic masculinity", and you happen to be from a fraternity that seems to you like a healthily masculine environment and have never seen a toxic one, then you might interpret my criticism of fraternities as coming from a viewpoint that masculinity itself is somehow intrinsically toxic, and interpret my sentence accordingly.
We've changed technical terminology before for similar reasons (eg. global warming -> climate change); it's probably worth finding a different term for this one.
