Found an earlier article by El Observador before the legislation passed. Under Uruguay’s old laws Spotify, YouTube, an other streaming platforms paid little to nothing in artist royalties. With the new legislation artists will now see fair compensation.
The Guardian does a better job explaining Spotify’s problem: do the royalties come from rights holders (I am assuming they’re referring to record labels) or the streaming services? The later case they believe will cause them to pay double what they’re paying for streaming rights.
The issue just needs to back to Uruguay’s government to sort out who pays the artist royalties, or if both labels and streaming share a proportionate responsibility.
The short version is that there are two images and sidecar/xmp file sandwiched into one file. First is the standard dynamic range image, what you’d expect to see from a jpeg. Second is the gain map, an image whose contents include details outside of SDR. The sidecar/xmp file has instructions on how to blend the two images together to create a consistent HDR image across displays.
So its HDR-ish enough for the average person. I like this solution, especially after seeing the hellscape that is DSLR raw format support.
