Those are definitely high, especially the 1080p number.
Common HEVC bitrates would be like 3-5 Mbps for 1080p and maybe 10-12 Mbps for UHD.
At least, that's what's commonly seen in the premium OTT streaming case. Approx 8 for FHD and 25 for UHD are the highest used in large scale streaming services.
I think this is enough for very good quality with most content with slow settings, but some challenging content really does need 30+ to look really good, especially grainy content. There's a reason UHD BluRay has the bitrates it does I guess
Anyway, I guess to sum things up, maybe for UHD BluRay level bitrates SAO doesn't make sense, but for anything practical for streaming you definitely want it turned on these days.
IMO.
