Changing size of graphics within the tiles/icons in start menu

Hello,

Here is my start menu:

I cannot find how to make the icons for apps larger. For no apparent reason, the Opera Browser icon (the actual icon, not the blue tile) is larger than, say, the Adobe apps. And the 'Live Tile' icons are lovely and fill the tile.

Is there any way to control the size of the icon within the tile? It seems silly to have great big blue tiles, with a tiny little icon sitting in the middle of each one. I've searched around, but can only find information on how to alter the size of the whole tile, not the icon within it.

Thanks in advance for any suggestions!

This is what I'm trying to achieve:

I found this: TileIconifier v2.2 - Native tile shortcuts t | Windows 10 Development and Hacking
...which works a treat!

It's still a bit odd that I have to go through this process just to tweak an icon, but nobody said using Windows was easy!
