Sure the size doesn't mean enjoyment. And sure it can always improve... but I was talking about sound quality and pixel+IQ (sure raytracing and even more advanced will take even more)... but for regular people it is quite close already.

Actually raytracing will take less. No more need to bake in global illumination which is what's bloating games like AC Unity, Forza and GTS. For sound quality, there's a chance that will be the next bloat as ray casting for physics based sound reflections will probably first need the same pre-bake solution as global illumination is using now.

Sure I just remember those lists back in the day it is hard to find them like this one for example:
It is all confusing because I see people discussing that some aren't really 4k but are upscale to 4K etc.

Whether the source is upscaled or not doesn't really matter.
Consider this, uncompressed 8 bit 1080p24 video runs at 1139 Mbps, compressed down to avg 25 Mbps on blu-ray, 2.2%
Uncompressed 10 bit 2160p24 video (4K UHD) runs at 5695 Mbps, compressed to avg 50 Mbps on 4K UHD, 0.9%
Both blu-ray and 4K UHD half the bandwidth before compression with 4:2:0 chroma subsampling, discarding 75% of the color information (only the color of 1 out of every 4 pixels is stored). So even if the source was upscaled to 4K, you still get 4x the color info compared to blu-ray, plus 4x the range with 10 bit per color. Both can't resolve fine detail in action scenes with that high compression factor.
Video games give you full fat 10 bit uncompressed output at 60fps which is 14,238 Mbps, or 13.9 Gbps. So sure, higher quality assets and bigger file sizes for games aren't so strange. Comparing graphic fidelity of video games through you tube videos, that is kinda pointless nowadays.

Well I am not an expert I just feel their is more going on when a blu ray movie is 50 GB in size (with almost no extra content) but you only use 14 GB to stream it on netflix =p.
