The story about Londontime and bad xrays comes up again and again.
I know people who have seen the x-rays when he was at the riding horse auction.
The way the horses are alreay insured at the auction and for that the x-rays are for sure part of the insurance checks… So I would need to ask these people (vets) what they have seen. I have also heard that he had laminitis prior to the auciton, but no clue if that os true or not.
But for what it is worth I would doubt that a lot of the stallion rearers look into offspring by him, if they would be known as having more xray issues than offspring of other stallions.
Since the same vet who has seen those xrays inseminated this mare and used him on one of her own, i doubt that there was an issue that has an effect on breeding or better to be inherited.
Regarding refinement: I would expect some, but maybe not in the way that some define it.
I would expect a horse with frame and hight but not like a barrel or tank. As one can see in both of the video, the dam has substance, but is pretty and refined.
