Well I can't argue your math but I can honestly tell you that I've had 8 bit VA and 10 bit IPS panels side by side and shown them to others for comparison. All agreed the difference was very noticeable. Being a display junkie I do have a growing collection of these things. The even odder thing is that I'm aware that supposedly true 10 bit support doesn't happen from NVIDIA or Windows except for professional apps. I've read that most games do not inherently actually have 10 bit color textures, etc., but again I've seen the difference. Anytime I sit down in front of a 8 bit panel things just seem more bland now after having had 3 different 4k IPS panels. Sure you can crank settings here and there but it just gives a washed out oversaturated effect similiar to turning up the color too far on an old pre-lcd t.v.
