Over the weekend, a system dump of the HTC One (2014) was performed by a member on XDA. As we have seen with previous system dumps, the world now has access to all of the wallpapers that HTC has preloaded with the device. Thankfully, they are actually pretty good papers.
From poking in the zip file, we can see there are lots of pretty photos taken of plants and waterscapes, as well as lots of geometric shape wallpapers. All of the colors will probably work nicely with the white icons and translucent bars on Kit Kat.
To use for yourself, download the zip file from MediaFire, extract (either on your desktop or your smartphone), then apply them as you would any other wallpaper.
Below we have placed a few of the wallpapers to give you an idea as to what to expect.
