Is there a database of CSS pixel ratio values for various devices?

Question

Is there a database of CSS pixel ratio values for various devices?

Here's what I want to do: when I get an HTTP request, check the server-side server database to find 1) the physical PPI device and 2) the CSS pixel ratio (that is, the number of “logical” or “links” of “pixels to physical pixel” This allows me to provide the requesting browser with a pixel value of 1 physical, real world inch.

Some things that I already tried did not go beyond:

http://wurfl.sourceforge.net/ : gives me physical size and resolution (so that I can calculate PPI) but not CSS aspect ratio.
http://51degrees.mobi/ : gives me physical size and resolution (so that I can calculate PPI) but not CSS aspect ratio.
https://deviceatlas.com - gives me PPI directly, but not related to CSS pixels.

Oddly enough, the best data source (free or paid) I found for this is http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density , but I want to get a more comprehensive and more tabular one.
