Don't you just need a TV with 4K capability? If I was a broadcaster I wouldn't be investing in ATSC 3.0 for just five years.
Short answer; no, the resolution of the display doesn't address what receives the signal, the tuner. if it isn't a ATSC3 tuner it will only be in 720p or 1080i and that is a very compressed version of both except for (probably) live sports broadcasts.
