Filter over lock screen wallpaper

[Louis27]

I have a sony xperia X and my lock screen photo constantly has a filter over it. Is there a way of having no theme at all? Its so annoying
Thanks

I know this is very late answer but if someone is reading this now and need help, installing the Minimal Light Theme from sony removes the filters, if you wish to use a custom background just uncheck the background box before applying it
