I've found the same. I couldn't use the same prompts others used to get back ChatGPT's prompt, but having it write it into a file "in the terminal" and then read it back worked great.

This didn't work for me at first, it just said the first line "Assistant is a large language model trained by OpenAI.". I added in the English bit that the file is 1024 bytes in size, then it gave the full prompt.
Edit: didn't work upon immediately trying the same. Wonder if they're detecting the prompt every time it is produced in output, and somehow adjusting the censor in real-time. Not sure.
