Plus on top of that keep in mind the 90fps and 120fps scenes will use roughly 50% and 100% more internet bandwidth to stream that the 60fps version of a scene.
This should not be the case, of course you could encode the same scene with 50% and 100% higher bitrates, but this should not be necessary to get the same quality.
Video compression basically works by storing basically reference frames (so called I Frames), which are basically similar to JPEG and are frames on their own. Then there are P(redicted)-Frames, which only store the difference to the frames before, and therefore can not be rendered without knowing the I-Frame before and modern Codecs also have B(idirectional) frames, that store differences to the frames before and after the Frame.
In a video file I frames take a lot of space, P frames a small amount and B frames only a very tiny amount.
Videos with higher framerates also mean much less difference between the individual frames, and therefore you do need relatively much less I Frames. Actually the amount of I frames should be nearly the same regardless if the video is 30, 60 or 120FPS, almost all additional Frames should be either P or B Frames.
So of course you need more bandwidth for higher framerates, but if the encoding settings have been reasonably it should be much much less then the actual increase in framerate.
