Capture NX2 question

http://www.earthboundlight.com/phototips/srgb-versus-adobe-rgb-debate.html

" If you use sRGB, you will be limited to colors that can be represented in sRGB. Even if you later convert to Adobe RGB, you won't end up with colors that were never captured."

If you have a file that is already set/converted to sRGB converting it to aRGB is pointless. Note the option in Capture NX2 says -convert to profile-.

"But Capture NX gives you a very poor way of changing it. You must edit your Preferences before opening the image to select the desired profile and check the box underneath to force NX to use it. There is no way to "try out" various profiles directly when opening an image. You can of course later use Convert Profile to select a different profile, but at this point the raw data will already have been limited to the gamut of the profile used to open the image."

And

"It seems more than a little odd to open a raw image into one color space, then use an Edit Step to later convert profiles using Adjust Profile rather than simply allowing the user to change the profile used to open it in the first place. I applaud Nikon for finally improving profile support in Capture, but the one color management control most useful for raw files is still poorly implemented. By contrast, Adobe Camera Raw, DxO Optics Pro and others allow you direct access to the profile used by the raw conversion engine."

Hence using "convert to aRGB" after a RAW file was opened in Capture NX2 as sRGB is totally pointless. The reverse however isn't true. This is an odd behaviour for RAW software and why I was asking this question in the first place.

Thanks to the links provided, I have my answer
