I don't think we use the term True Color in GIMP. But GIMP's RGB mode is
8bit per color channel, which makes 24 or 32 bits per pixel depending on
whether you have an alpha channel or not. That makes up for about 16.7
million colors.

No, the colors aren't specified with 24 bit hex values. Hexadecimal
notation is one way that humans use to specify colors. Computers only
know 0 and 1, and they need 24 of those to store an RGB color.
