Streaming services pretty much top out at 80Mbps, but more typically are around 15≃20Mbps for even 4K content, so even if they straight quadrupled the bitrate for 8K content you'd only be hitting UHD BD rates.
I don't disagree that BD will not exist for an 8K market, but that's because physical media is being killed.
This isn't even getting into the actual mastered resolution of much of this content, which you're lucky if it's even in 4K, most stuff is still mastered in 2K.
I've never tried 4K streaming (don't have the premium subscription), but 17.5 Mbps for 4K sounds like a joke. There are older 1080 sources (especially with grain) where you don't want to go too much below 15 Mpbs on H264. Even H265 generally works better primarily on newer sources material (post 2005) and encoding high complexity older film with H265 is going to give marginal efficiency improvements relative to H264.
what (legal) streaming service is giving such high bitrates? I thought they were giving like 20 at most
Sony Pictures Core, Kaleidescape, probably a few other niche ones.
