Terrain: Elevation tinted hillshade legend

[Oliver_Burdekin]

I'm using the Terrain: Elevation tinted hillshade image service in a map. Being an image service the legend shows as an RGB band combination.

In the description of the layer an image of a legend is provided. Is there a neat way to provide an informative legend through ArcGIS Pro or online from an image service or is the only option to insert an image of a legend?

I don't have an answer for you, Oliver, but I was just trying to figure this problem out as well. I'm hoping a comment might bring some attention to this? I was thinking I would take a clip of the legend from the info page here and paste it into my map, but that's not ideal. I'm looking at this one: https://www.arcgis.com/home/item.html?id=ad7e1f1787814a2abd5557ad24a66b22
