We only use the DPI setting when the file is printed (or exported to PSD). Internally we only use pixels, and just use the DPI setting to calculate how many pixels are required for the requested size-in-inches * print DPI to get a 1:1 match with printed output to pixels. (The rulers also use the DPI setting when in Inches, cm, or mm scale to indicate the sizes in printed output)
