This will definitely improve load times and reduce stuttering, might improve FPS and of course speed up download and extraction times. This is all thanks to improved compression and file optimization using PNGQuant and other tools. And Android/iOS users get an even larger improvement, with a mindblowing 2.7x reduction in file sizes. Even with mip-maps and re-conversion to DDS in the desktop version, TP 4K 1.4.0 is still a fair bit smaller than 1.3, even with all the new textures. Thanks to improved compression algorithms, all textures have been thoroughly optimized and reduced in file sizes, without losing any noticable quality. Heavily reduced file sizes (without sacrificing quality!)
New material maps have been created to give more surfaces and textures depth and more realistic reflections from lighting. This includes new map textures, icons, menu fixes and more. New UI textures include both the on-screen UI as well as the various menus and icons present all over the game. Including enemies like Tektites, Bokoblins and more! New UI textures! Several items have been re-textured, including the Bow, the Dominion Rod, Water Bombs and more.
There are several newly created textures for both Link and Wolf Link in higher resolutions, including the shields and swords, this also covers most of the alternate armour sets and weapons! New item textures!
