✅ How to specify camel case for all response properties with Newtonsoft

This is the type of JSON I receive from an external API:

    "phoneValidation": {
      "success": true,
      "data": {
        "number": "27101238765",
        "valid": true,
        "account_details": {
          "google": {
            "registered": false,
            "full_name": null
          },
          "twitter": {
            "registered": true
          },
          "skype": {
            "registered": false,
            "age": null,
            "city": null,
          },
          "whatsapp": {
            "registered": true,
            "last_active": null
          },
          "telegram": {
            "registered": null,
            "photo": null,
          },

    "phoneValidation": {
      "success": true,
      "data": {
        "number": "27101238765",
        "valid": true,
        "account_details": {
          "google": {
            "registered": false,
            "full_name": null
          },
          "twitter": {
            "registered": true
          },
          "skype": {
            "registered": false,
            "age": null,
            "city": null,
          },
          "whatsapp": {
            "registered": true,
            "last_active": null
          },
          "telegram": {
            "registered": null,
            "photo": null,
          },

This I deserialize into this DTO:

public class ValidatePhoneNumberReceived
{
    public bool Success { get; set; }
    public ValidatePhoneNumberData Data { get; set; }

    public class ValidatePhoneNumberData
    {
        public string Number { get; set; }
        public Dictionary<string, object> AccountDetails { get; set; }
    }
}

public class ValidatePhoneNumberReceived
{
    public bool Success { get; set; }
    public ValidatePhoneNumberData Data { get; set; }

    public class ValidatePhoneNumberData
    {
        public string Number { get; set; }
        public Dictionary<string, object> AccountDetails { get; set; }
    }
}

Then I do some stuff, and return the same model from my own API. AccountDetails contains object, because for each key, the external API returns a different set of properties, as we see in the json account_details.google, and account_details.whatsapp etc. They appear in my response with the same snake case I received them with. I have even tried adding an action filter to add a NewtonsoftJsonOutputFormatter set to camel case. How can I force the dynamic properties to be camel case?

c#
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;

var settings = new JsonSerializerSettings
{
    ContractResolver = new CamelCasePropertyNamesContractResolver(),
    Formatting = Formatting.Indented 
};

var obj = new
{
    FirstName = "John",
    LastName = "Doe"
};

string json = JsonConvert.SerializeObject(obj, settings);
Console.WriteLine(json);

Seconding the viability voncerns about converters: Notice that camelCase AND snake_case are being used.
