I can't offer an educated guess. Don't know where you live (I had no idea Dumphries, VA was in Michigan), what the affiliates are or even if DirecTV has them. I have no idea who your other MPVDs are nor how heavily compress channels. I don't have the education necessary for an "educated guess." Those who do... live there. You'll really need to find one of them. There is no "broader look." Only a specific one to your area and I don't have any experience with it outside of watching stations in hotels when I used to go to the UP back in the day.
If your goal is a great picture from your local stations, you're stuck with what they spit out. Take WJMN in Escanaba, for example. CBS 1080i, but with FOUR subchannels. Being Escanaba, I can almost guarantee you WJMN doesn't have the latest-greatest encoder. Almost. It's a Nexstar station, so it's possible they have newer gear, but not THAT much newer. Being Nexstar, it might be off of DirecTV due to the carriage dispute. I don't know. I don't even know if that's where you live. I'm just saying a small-market plant shoving CBS and four subchannels into one ATSC stream ain't gonna look great on a 65" OLED TV, no matter what MPVD's carrying them. Garbage in, garbage out.
You have other priorities to figure. DirecTV has the most 4k linear programming, but you live in the Land Of Nearly Constant Snow. If you can't put the dish where you can get a broom on it, that's gonna be an issue. Which might be why all of your neighbors have cable.
Cable has no 4k. Likely won't, especially in smaller markets. If you're in a Comcast area, Xfinity is starting to move in that direction. Useless without a pretty decent broadband pipe, though.
If I were you, I'd just call your local station's engineers and ask them. They always get feedback. Usually from station employees.
Or give up live network programming. Follow Johnny Antenna's lead. Hulu, CBSAA and others give you day-or-so after programming often with better PQ. YouTubeTV is saddled with the same thing as other MPVDs. They can only give you what they get from affiliates, assuming your market's even available.
