CMYK image colour changes post image resize

[vaidhyanathan-ananthakrishnan-13]

The version used: v2.7.0

For a set of images, If I resize the image using the govips , the CMYK file's color is changing drastically, but for the same image when I tried using the libvips command line, it is working fine.

Original image: https://raw.githubusercontent.com/vaidhyanathan93/Todo/master/5000.jpg
Resized image : https://raw.githubusercontent.com/vaidhyanathan93/Todo/master/Resized.webp

Lib vips command line

vipsthumbnail 5000-1.jpeg -s 540x439

Before transform image call function OptimizeICCProfile()

img, err := vips.NewImageFromReader(reader)
if err != nil {...}
if err := img.OptimizeICCProfile(); err != nil {...}

Tried with OptimizeICCProfile but got the error below

Error, i cant reproduce, but got same problem with colors after transform.

After reading code i found out, this part of code works strange.

Why we should ignore embeded profile if image has it. It's true only for images with CMYK color space

@Elad-Laufer can you look at comment above. Why did you prevent using embeded color profile at image with CMYK color space ?

Is there any workaround for this ?
