i am more than well aware of all of this. nothing i said is misinformation. same algorithm, different settings. the primary means by which you reduce bitrate with h.265 is by reducing the quality setting. there is no magical way to cut your bitrate by 75% using the same compression algorithm without sacrificing quality. no commercial streaming service is offering video at the same quality level as a 4k blu-ray.
few streaming boxes even support dolby vision profile 7, and no commercial streaming service offers it. so saying you can get it through a streaming service is actual misinformation.
i have literally been doing this shit for 20 years
