To everyone:

AMD cards dither the output by default, but you can disable it:

Check the Catalyst Control Center under "Information" -> "Software" to get the 2D driver path. Then run regedit.exe and open that path in the left pane. You should see values in the right pane like "AdapterDesc" and a bunch of settings. Add a DWORD value named TMDS_DisableDither (for DVI) or DP_DisableDither (for DisplayPort) with a value of 1
HDMI_DisableDither for HDMI. Reboot after.

Only that can explain why I see a difference between 8 and 10 bit output on my 6-bit DELL U2212HM connected with DVI
