Some are good now (if set up correctly). Illustrator, Photoshop, Affinity Designer, Affinity Photo, Pixelmator, and Acorn all handle things well, if you have the correct profile attached to the document.

It does become a bit of a challenge when you need to not only understand the colour values, but also which profile they’re using. It can get pretty tricky.

It’s definitely also worth noting that at one point Safari wasn’t colour managed (or to be more accurate, had all kinds of wild behaviour). This stuff has changed a lot over the past decade, but it’s all heading in the same direction, thankfully!
