I've looked at the file Fondo_02.pdf. It does contain a mesh with 143 patches. This kind of mesh cannot be imported into Inkscape as a single mesh as SVG meshes require a grid structure and the 143 patches don't form a grid with a constant number of rows and columns.
The current "native" PDF importer converts a mesh into a group of "tiles". Each mesh patch corresponds results in one or more tiles where each tile is a path object with a solid color. (The number depends on a parameter set in the PDF import dialog.) It is possible to change that so that each patch is imported as a path object filled by a mesh with a single patch. It should also be possible in the future to turn off automatically the anti-aliasing for the patches.
Eventually, SVG 2 will allow multiple fills for a single object in which case one could have one object filled by multiple single patch meshes.
