Throw distance

I am a little confused with manufacture definition of throw distance / ratio when it comes to 16:9 vs 2.35:1 screens. For example:

PJ manufacturer lists 1.4 to 2.8 throw ratio
PJ Native resolution is 1.90 (4096x2160)

Let’s assume one is using a 2.35:1 scope screen, say 100” width. Is the MINIMUM throw distance really just 1.4x100= 140” to perfectly fill this scope screen ? This seems too simple- doesn’t the projector have to zoom in even more than 1.4 to stretch the native 1.90 panel to fit the 2.35 screen ?

If so, is it accurate to say the manufacturer throw ratio only applies when the projector is lighting up a screen with an identical aspect ratio as its native panel (1.90:1 in this example) ? If that’s the case, why aren’t different throw ratios listed for all the common screen aspect ratios ?
