Regarding HTP according dpreview (see reviews) does affect raw - that's why lowest ISO is 200, and then you have to process with a different tone curve. It does affect the dynamic range giving a bit more range in the highlights (see dpreview tests) .

No, sorry, you misunderstood what they said, and they didn't write it very clearly. It affects the ISO setting and the exposure, but otherwise it doesn't affect the raw file. It doesn't do any processing to the raw file. If you save only to raw, not jpeg, you can get exactly the same effect by doubling the ISO setting and reducing the exposure by one stop. I've done careful testing on this, and can verify it. But I'm not going to discuss it further.

yes, I understand that part, that's my understanding as well. But the key is that the 1 stop underexposure is "burnt" into the RAW (unlike cameras settings, which don't report 1 stop underexposure), together with (totally guesswork here) some flag that later instructs that a different tone curve is applied during processing. Of course you can develop RAW as you like.
