I mean, if you have a strong mental imagery, it's not ambiguous at all whether it's metaphorical or not. It really is seeing. All experience is subjective, but it's like if half of people were seeing in greyscale and tried to argue that there may or may not be different colors other than grey, and that the discussion is pointless. The people seeing colors are like, uhhh no man, there are actually different colors and you're just not seeing them. It's incredibly obvious that there are more colors than grey. But when a large chunk of people see in monochrome, and even more people are seeing an extremely desaturated palette to where it's almost grey but not quite, the discussion gets muddied. And then the greyscale seers try to convince everyone that it's just a difference in language and actually 'red' is just a feeling. It's just absurd to anyone who has the strong sense.
