With lossless compression and the "modern" internet, it is a matter to indeed allocate more to image bandwidth, from an internet point of view, that would be the price of 'end game' image format quality (lossless and 16bits per component).

You are missing critical metrics: the absolute values which are now very important in our super high speed internet and beyond powerfull consumer hardware.

It is a bit like linux on steam: 6%... but millions, ratio is little, but the absolute is so huge that it you cannot ignore anymore their market value (like macOS though).
