Acer Nitro 5 AN515-51 laptop display bit depth (6 bit?)

So I'm trying to find out about the bit depth of this laptop's display.

Since this is an IPS display and not a TN one, I was expecting 8 bit depth. But when I checked the settings I got this:



But in the meantime, when I'm searching for the display modes, I get this:



Can anyone tell me what's up with this display? Is it 6 bit indeed?

As far as I can make out, your IPS panel is 6-bit but it can display 32-bit through the use of dithering.

See this page for a good mathematical explanation:
LCD Displays and Bit Color Depth

dithering: " This is an effect where nearby pixels use slightly varying shades or color that trick the human eye into perceiving the desired color even though it isn't truly that color. "

One thing to note: 6 bits would be per RGB color, so that'd be described as 18 bit color (262,144 colors). 32 bit color is really 8 bits per RGB color (24 bits, 16.8 million colors) plus an 8 bit "alpha channel" (transparency).

Colors derived through dithering are real enough, but they are trading off spatial or temporal resolution to achieve the extra bits.

Yeah, I know what's what. But I was just expecting IPS monitors to be 8 bit, since my TN one was 8 bit.
