There are plenty of DPI/TM solutions that identify and classify the protocol very quickly and efficiently, every ISP today does it. It's highly unlikely that a Saudi or any modern telco would would not be able to analyse the traffic and extrapolate the exact protocol and application from it as well as other information such as if it's an encrypted stream or not (heck testing if data is encrypted or not is as simple as running compression on random samples and checking the compression ratio, you'll have to classify if the data is compressed to begin with but if it's not compressed data and it's not compressible it's quite likely to encrypted).
