@mariusor @oranadoz @hongminhee right, but here a description of the icon isn't the same as the binary of the icon itself.
The binary gives you very different data to the description of it, e.g., fetching the binary doesn't indicate where to send replies to or how to interact with it; where as html <-> json-ld generally gives you similar enough representations.
Generally con-neg suggests the same data just in different formats; what you're giving here is different data in different formats.
