It would be interesting to know how many people use the tuner in their TV rather than cable, streaming, or the one in their DVR. Our TiVo use was supplanted by DIRECTV streaming in the past few years, but I don’t think I’ve used the built in tuner in about 15 years.

Is there any regulatory reason to include tuners in displays?

I wonder if something like this https://www.raspberrypi.com/products/raspberry-pi-tv-hat/ could be used with the RPi capability
