Every dcat:mediaType is a kind of schema:encodingFormat, but not every schema:encodingFormat is a kind of dcat:mediaType. The reason is the domain of dcat:mediaType is a dcat:Distribution. A dcat:Distribution us equivalent to a schema:DataDownload, which is a domain of schema:encodingFormat, via schema:CreativeWork. But schema:encodingFormat has a second domain, of schema:MediaObject. And the use of encodingFormat on MediaObject is not equivalent to dcat:mediaType. The problem with the alignment is that it is symmetric, but the real world isn't. By changing to a sub-type we keep the alignment in the correct direction only.

Every dcat:mediaType is a kind of schema:encodingFormat, but not every schema:encodingFormat is a kind of dcat:mediaType.
The reason is schema:encodingFormat has two domains, only one of which is equivalent to dcat:mediaType's domain of dcat:Distribution. A dcat:Distribution is equivalent to a schema:DataDownload, which is a domain of schema:encodingFormat, via schema:CreativeWork. But schema:encodingFormat has a second domain, of schema:MediaObject. And the use of encodingFormat on MediaObject is not equivalent to dcat:mediaType.
