On Windows, the default screen DPI (aka PPI) is 96. On macOS, as far as I know, it is still 72 (note that we talk about images, not text!). Because of this, when I open InDesign on Windows and place there a 72-dpi image, it looks larger (compared to how it looks in web browser, hence web browser doesn't care about DPI) and blurry.
Does it also mean that if I open InDesign on macOS and place a 96-dpi image there, it will look smaller compared to how it looks in web browser?
And does it mean that if I create an InDesign document with 96-dpi images on my Windows PC, and then send it to a friend who use Mac, the images will look wrong (that is, smaller) to him?
I don't have a Mac, neither do my friends (just because it is quite pricy in my country), so I can't test it myself.
