I have no experience with it, but you could try colord-kde
https://packages.ubuntu.com/hirsute/colord-kde
I quickly loaded it, and it provides a picture and various settings (that alter the colors in the picture), once installed a Color Profile Viewer appeared in the System Tools menu on my test system; but it appeared to be operated from terminal. It mentions ICC Profile, but I have no idea how you’d make use of it sorry.
I didn’t explore what already existed on this forum earlier; but the link may contain more detail
