I have done a couple.
Fortunately the larger job was a remodel on an existing/returning client's house and was able to call out space and conduit for the One Connect boxes.

Was able to house 1 in a rack next to the fireplace (semi local system), 2 were able to make it back to the main rack with longer One Connect cables and the 3rd I lopped a hole in the wall and stuck it in a back box. The last one was the biggest PITA as it was a smaller one (55"), had specific mount requirements (flush but long throw articulating) and they (of course) had just wallpapered the room when he decided to add the tv. No pressure to not mess up (sigh).

Two of the locations came out amazing. Both 75s, one on an all white paneled wall that the spacing of the trim was designed around the dimensions of the display (white frame), the other's frame was an almost perfect color match to the mantle and cabinetry.

Client was super happy with the results. And I got to make money off tvs, haven't had a whole lot of that for a while.
