Features / Usability

The documentation — at https://doc.tiki.org/PluginSlideshow#Slideshow_Theme_style — says the theme can be switched. Did you try that? Maybe there's one that's close enough. Otherwise, I don't know. As for a custom background and header, I suppose that might require checking out the theme files in the slideshow library and duplicating/modifying one, or maybe the colors, etc. could be overridden with new CSS. That would take looking at the slideshow using a browser's DOM inspector or web developer tools, to inspect the header and background and identifying the CSS selectors involved, and adding custom CSS in the Look and Feel admin page's customization tab.
