问题 I'm working on a project where I've had to learn about color profiles a bit, still very much a novice.

I understand the "best" thing to do is convert the src.jpg to sRGB colorspace. I've tried both command line using convert and Imagick approach using transformImageColorspace() and find it works fine on my local machine (Fedora 32 Linux) but doesn't work on the production server (CentOS 7.3 Linux).
