None of those should have any effect on the RAW image. Those are in camera or in computer processes which get applied to the conversion from RAW to a jpg. If you read this Adobe document you should get a good idea as to what the RAW data is all about.

The most important thing to remember about using the RAW image (actually data) is that you can re process it over & over without altering it. Each time that you run it through your software you create a new image file in any of several formats but you don't actually alter any of the original file.

I'm sure that Long exposure noise reduction is applied to RAW images. It's using dark frame subtraction so it will affect RAW images.

It's very possible you're correct but all I can find about it are discussions claiming that, but no definative proof. Do you have any further info?
