Slideshow option to remove blurred / black bars on photo slide show

It would be nice to have the Plex photo slide show provide the option to zoom in on photos that don’t take up the entire TV screen to remove the blurred background on it. Xbox 360 provides the option when using it as a Windows Media Center to automatically zoom in and fill the 16:9 TV screen with the entire photo for those that were not shot in the 16:9 mode but rather the 4:3 mode.
