Channel icons like material designs

This dashboard uses buttons to run a script, which sends infrared commands to my set-top box to change the channel.

I would like to replace the existing icons with the actual channel icon.

I know it’s a long-shot, but any chance these channel icons exist somewhere, in consistent form, like the ones in Material Design Icons?

Thanks

In the past I’ve pulled channel icons off the direct TV site. They typically have channel lineups for the various packages they sell that you can browse through. I suspect they are likely bitmaps but you may be able to convert them or use them directly.
