LSR file for tvOS Top Shelf Images?

Based on the got layered PNG files for my icons and they work great.  However, I’d like to create a .lsr file and use it for the top https://elecpay.in/tneb/shelf images too…  Getting read https://birthdaywishes.onl/y to try this out but just curious from your end if there’s anything special I need to do other than this? 

topShelfImage = “Icon-tvOS-TopShelf.lsr”, – 1920x720
topShelfImageWide = “Icon-tvOS-TopShelfWide.lsr”, – 2320x720
