On a road bike (an R1) I put a Power Commander on it and found a file online that near enough matched all the go-faster parts I had fitted. Rode fine for a summer then took it to A dyno with my ZX10 racebike.
After the ‘custom dyno’ tune it gained 4hp in the midrange and nothing anywhere else. Perfectly fine for a road bike. I think generic are fine for a diesel estate car..
Spent many thousands extracting minimal power gains on the ZX10 though!

I have done similar with a dynojet PowerVision and a stock map, then a lot of "autotuning" runs and you are right - it gets pretty close. Then a bit of tweaking various tables for timing etc and I think you can get 95% of the way to a dyno tune.
Even so, I have always got better when putting the bikes on a dyno.
But you are right - for a diesel estate, a cookie cutter map is probably good enough!
