You are 100% false on this one, especially with GPT-4. I can take entire vanilla JS functions, and ask the language model to rewrite them using typescript, snake case naming conventions, and show it a block of other code that I've written to adhere to the same structure including jsdocs and it nails it nearly every time.
In your example, you are asking GPT-4 to rewrite code from one public style to another public style. I was saying that LLMs cannot reflect your personal style, because they know nothing about it. Even when instructed at length and provided with short examples (that fit in the context window), they always gravitate to the public average.
