The only drawback using Daz models is even the high res skin textures aren't very high, so if you have to zoom in close like for an orthopedic procedure the skin starts to get blurry, not to mention no detailed normal or bump mapping. But it is great quality for next to no cost.
There are plenty of 4K res textures available thru Daz, but like you say, zooming in super close it will break up. But really, you're not going to find many models out there that come with 6-8K+ texture maps (at least I haven't---maybe on turbosquid?).
For those I create my own using resources like 3dsk http://www.3d.sk to work from.
