While extreme high ISO is usable, and I do use ISO 25600 on my 5D MK III if I have to, much of the fine detail is lost, and more is removed by NR.

There are lots of test photos done by professionals that let you compare at different levels of ISO and NR so you can judge the results.

The other issue with high ISO which your studio photo does not illustrate is the very shallow amout of DR. Only about 5 stops of DR. This means its very difficult to capture bright highlights and shadow areas, and requires a lot of post processing.

A related point would be color fidelity and tonality, just as the "brightness map" suffers at high ISO the colors calculated from it during demosaicing take a hit, although more subtle and imo more damaging.
