For streaming, probably true. However my 2016-era 4K camera records at up to 150Mbps and I noticed recently that due to compression I was totally unable to show off some gorgeous telephoto video of a hummingbird bathing in a river because the fast running water looked truly horrible under compression, even though the original video looked great. I would love 100mpbs streaming options.
Bitrate on a camera and on a video aren't comparable. The camera has to use a compression algorithm that can run real time on very low power (the cpu in a camera is probably ~5-10 watts. Anything non-real-time video will have been re-compressed and can probably maintain quality at roughly half the bitrate.
