Dapper typehandler when returning dynamics

Question

This does not work:

public class DateTimeHandler : SqlMapper.TypeHandler<DateTime>
{
    public override DateTime Parse(object value) =>
        DateTime.SpecifyKind((DateTime)value, DateTimeKind.Utc);

    public override void SetValue(IDbDataParameter parameter, DateTime value)
    {
        parameter.Value = value;
    }
}

Dapper.SqlMapper.AddTypeHandler<DateTime>(new DateTimeHandler());

var res = connection.QuerySingleOrDefault<dynamic>($@"SELECT some_date FROM table");
// outputs Unspecified
System.Console.WriteLine(res.some_date.Kind.ToString());

This works:

public class ViewModel {
    public DateTime some_date { get; set; }
}
var res = connection.QuerySingleOrDefault<ViewModel>($@"SELECT some_date FROM table");
// outputs Utc
System.Console.WriteLine(res.some_date.Kind.ToString());

Any way to make typehandlers in dapper work when querying as dynamic?
