only if youre displaying the picture at the same size as it would be after printing which no one ever does and no browser out there ever has done and will ever do
browsers always display images per pixel while completely ignoring the dpi info in the file
and if youre editing a picture most of the time youll either display it at a size where 1 monitor pixel is much much larger than 1 pixel of the image to get good detail in print while letting the editor handle all the nitty gritty sub pixel stuff or in case youre working with very low res images (which almost no one does these days but theres a few something or other done in paint videos which do just that) youll most likely blow the diplayed image up a lot so each pixel covers a considerable amount of your screen real estate
ppi means nothing for how a web page or an image gets displayed on your screen
the only thing you can measure with ppi is how far away you have to place the monitor if you take your glasses off
