Vegas changes color on output when frameserving

I want to Frameserve a video from Vegas by Debugmode Frameserver. It is an mpg file. I try frameserving into Avisynth. The problem is: if I open the mpg in Vegas, do nothing, just frameserve it right away, and open in Avisynth, the colors are changed. They are different than in case I open the mpg directly in Avisynth. You can see them in the photos attached below. When I run the video through Vegas first, I loose saturation. You can see it on the photos. Something should be set in Vegas not to change the colors, but what? In Debugmode Frameserver I have 3 choices: RGB24 RGB32 and YUY2. I am frameserving through YUY2. I tried the other two options as well but they do not work differently.

I have Vegas 12 on Windows 7.

This is from Vegas:

With Vegas 12 there is no quick answer to levels. It's "on you" to correct them so that all media has the levels expected for the media type when going from program to program.

You will need to add a Levels filter to adjust the levels of the AVI file that is being frame-served so the receiving application sees a proper full range signal.

Where you do levels adjustment in your workflow can be convoluted and complicated.

Start Here. Vegas Pro Levels, Last and Final # 1

Upgrade to Vegas Pro 18 or above when you're able.

I was suggested to Add "Levels" filter and choose the Preset: Studio RGB to Computer RGB. That solved the problem indeed, now the output colors match the case I open the mpg in Avisynth directly.
