At least where I live, there's no extra information being gathered. The only difference is that I no longer have to physically go somewhere to deal with that information, because I can sign in to government services online.
Information that was previously in paper form and scattered across various bureaus is now being digitised and centralised, but that's orthogonal to "digital ID"!
I don't see how that's the case for digital ID by itself. I'm also pretty sure that we can analyse the impact of a single technology without also blaming it for the downsides of other, distinct policies.
