Right color map opening a tiff

Add-Ons
1

Hello all!
I need a tiff image (cmyk) is opened with the correct colors.
I’m using

p=f.OpenAsTiffMBS.Pict

that opens the image but with wrong colors (example: cyan become green…).

Is there a way to open it with right colors as “Preview” do?

Many thanks

for CMYK you need to do color matching.
We have example projects for that included with plugins.
