If you are connecting over an Ethernet LAN you probably *won't* see the speed improvement; even the reduced bandwidth being used is completely swamped by the time spent in the encoder.
If you tweak the "deferral" settings, designed to save updates for so many milliseconds before sending it, then you would decrease latency, make use of more bandwidth, and you might then see a difference between 8-bit and 24-bit.
(What are those settings, you ask? I don't know exactly. My notes on VNC settings are spread all over the place. I am planning to consolidate them soon, probably into a web page.)
