I had my doubts but that is really faster, it'll require less data (reads) from stream/file.
The big difference is from both parameters useEmbeddedColorManagement and validateImageData set to false.
Tested with a 195001 bytes JPEG, the original load Image.FromStream(fileStream) did read all the bytes from the stream and the Image.FromStream(fileStream, false, false) version did read only 4268 bytes (about 2,1%).
