Your image is loaded into a canvas who does not preserve any metadata. The color profile and metadata will be lost. Be careful if your source image is not sRGB, the colors you will get back won't be the same.

You could use a lib like sharp js to extract and maybe inject again metadata.

I suggest that you read those SO answers :
