Changing JPG quality and DPI has no effect at all #28

I've done several runs with MBTiles of the same area at zoom levels 12-14 with different JPG qualities (75-100) and DPI settings (96-300). None of these changes had any effect at all, neither on the visible quality and resolution nor on the size of the destination file (which just proves my visual judgment). The quality was always as bad as with the 75 % and 96 dpi.

Let me open a ticket in QGIS, as this repo is just a placeholder....
