It is extremely track dependant.
For instance, I've just been doing the Formula C championship and the first track is Brno GP. It is almost completely silky smooth with very little detail and "road feel". The corners are also a bit strange and not all that natural feeling. Thus this track is a great example of one that has "no details". Unsurprisingly it's not laser scanned.. hand made by somebody who perhaps doesn't have all that much experience with tracks or it got rushed in the end and never got extra bumps and textures implemented.
Then on the flip side, try driving the Formula C with my FFB file around Nordschleife or Nurburgring GP. Those are properly laser scanned (same data set that Kunos and many other companies used) and thus the detail and "road noise" is insane. The corners are also properly banked in all sorts of manner which helps with the feeling of tire load.
Some examples of "textureless/dead" tracks:
Brno
Silverstone
Spa (it's a bit inbetween)
Monza
Ruapuna (has some parts with some vibe.. but quite smooth overall)
Road America
Some examples of properly "textured" feeling circuits:
Algarve (laser scanned)
Oulton Park (laser scanned)
Nurburgring GP (laser scanned)
Nordschleife (laser scanned)
Bannochbrae (one of the better fantasy tracks)
Snetterton (laser scanned)
Cadwell Park (laser scanned)
Knockhill (laser scanned)
Fuji Speedway (laser scanned)
Sportsland Sugo (laser scanned)
Red Bull Ring (laser scanned)
Circuit of the Americas (laser scanned)
Indianapolis Speedway (laser scanned)
Texas Motor Speedway (laser scanned)
Watkins Glen (this is NOT laser scanned but has good road features and sensible cambered corners)
etc..
My point is that what you describe as lacking varies immensely between tracks. It also varies immensely between cars, of course. If you drive a family saloon around Nordschleife it'll feel silky smooth compared to the Formula C which is a very rough ride. This is one thing pCars 2 does much better than any other sim in my opinion. There is TRUE differences in FFB feel depending on suspension/damper settings on the cars. Very few sims manage to convey all of the subtleties of this as well as pC2 does through it's FFB.
.. this is also partly the reason why some cars feel slightly "dead". The suspension + damper + aero setup may not at all be optimal and as soon as you get a truly objectively good setup going (objectively measured through telemetry and consistent laptimes) you suddenly get a lot more detailed FFB and clearly feel tire loads.
Finally temperature and wear of the tires plays a huge role in pC2. If you get the tires too warm or too cold it all will feel a bit "mushy" and non-detailed, just as a real tire does! When the tires fall into that magic optimum temp window you immediately notice it!! On race cars in cold weather it is very important to drastically close the brake cooling ducts so that you get your brakes nice and hot as these help to feed heat into the tires.
TL;DR
It's is super complicated. There is no easy answer or generic objective "opinion" on this. In some cases there is very little "road feel" due to various complex factors and sometimes there is superb road feel due to various complex factors.
