There is, in my opinion, only one nuance: whether your data, which has been provided for KYC, can be used for purposes that may cause you harm or loss. For example - can your data be used for illegal activities. For example, pretending to be you - when registering a car accident, obtaining a loan, or similar actions.... If such actions, with that set of your data, cannot be performed - what are the risks?
I will say by the way - in hospital, in internet stores, in banks - there is much more information about you, and it is more accessible than KYC data
