I don't see this being such a big gap. There are some use-cases for sure but apart from UX/UI work it is not really needed. Besides, none of the frontier models can replicate actual images - the can approximate at least in my own experience.

One of my tests for a new model is dumping in a screenshot of a web page and seeing if it can recreate it from scratch in HTML and CSS.

Even the local models I run on my Mac are getting surprisingly good at that now.

Using llms to generate docx. Being able to rasterize and review is an important part of the process.
