All the tests here are in cabin. And they only claim that RTF tires isn't as noisy as people believe since the BMW is so much quieter even on RFT.

Change the RFT on the BMW, to the same brand 'non RFT' specification and users have found the non RFT version is much quieter.
As said, typically the stiffer tyre does come though with more NVH to the cabin.
The Golf can't be a comparison, as there is no benchmark for NVH, against the BMW. So meaningless, other than a 'drive by' sound level.
