Not OP, but I am a radiologist, and that 3T image is not representative of a state-of-the-art clinical scanner. The 11.7T does have extremely high spatial resolution but contrast resolution is compromised.

As others have said the clinical utility of >3T is very dubious, and most real world MR advances in the last 5 years have been AI (DL/ML not generative) reconstruction for lower field strengths.

That high a field strength has significant safety concerns, particularly for implants and pacemakers etc.
