You need to look at this dpi thing a bit closer
2048 x 1536 pixels at 72 dpi means an image 24.444 x 21.333 inches.
The same information may be presented as
2048 x 1536 pixels at 300 dpi is an image 6.827 x 5.120 inches
If you look at your Gimp preferences you will see that the default resolution
for presentation is 72 dpi. Change that to 300 dpi and reopen the image
you will see the size of the picture as above.
As you can see, dpi is fairly meaningless. It is what you want it to be.
What is important is the total information in the image.
