We have had a couple requests for showing the result count in media search. I don't think this is a critical ask but do see its usefulness for gauging the success of your query and what to expect.
I think we have plenty of space to show it to the right off filters on desktop like this:
On mobile web, it's a different story in regards to our real estate. I don't think it's worth creating a whole new line and pushing the results even farther down the page. I would be fine hiding it on mobile.
The only alternative I can think of is placing it at the beginning or end of filter row. The beginning would push filter usage to be more hidden and less used and putting it at the end would be nearly undiscoverable.
