Then do that. It's not a video codec. The problem is computation power is increasing much more slowly than bandwidth, and is likely to continue to. 8K PNGs (by my napkin calculations) already take around 1 second of CPU time to decode. There are other solutions, and certainly better options today, but it's plausible that in the next 10-15 years, this will become the best option for fast-loading, high-resolution, 2D images. (Or texture data for 3D graphics. Or 360, I guess - not sure why that'd be different.)

PNG isnt good at multi threading or GPU decoding, thats the issue

If that was the only issue, they could tile the images up into 4 or 9 images in many cases.

It's a huge issue, but multi-threading only helps with latency, not energy.
