Is it enough to show a 10-bit luminance pattern by setting Window(...bpc=(10,10,10), depthBits=10)?

I’ve read in some other replies in the forum that pyglet, psychopy supports 10bit display now, but I haven’t seen any specific settings, so I’d like to ask if you can share the details of the settings and if it’s been tested to actually display a 10bit luminance pattern.
Thank a lot.
