Not really...At the time when Sherlock Holmes was writtern by Sir Arthur Conan Doyle, the resources were less. Forensics were at its birth stage. There were no DNA tests. If it was so in Conan, many cases would remain unsolved. Also Gosho has derived most of his stories from famous Mystery novels and stories.
In Episode 1 itself, Shinchi say "Holmes was a perfect dtective", that is, Gosho himself says Sherlock Holmes was the best...even if in fiction.
