You already have your answer, but I'll confirm with another detail.
I use the advanced desktop UI (the one with the columns) and it not only takes up a large space in the feed, but when I expand it, it is expanded but super narrow with no way to zoom to 100% on a click, so it's illegible on both the timeline and on the click.

Lack of zoom makes detalized photo and, especially, art sharing here a lost cause, IMO.
