Are you sure of your definitions ?
A RGB image 24 bits per pixel (bpp) is 8 bits for each of R , G , B in each pixel and that is also the RGB format for the gif palette. In Gimp from the Gimp menu Image -> Precision that is the 8 bit setting and also what you are probably seeing top of the Gimp window.
Where it gets degraded is a gif is color indexed and uses a maximum of 256 colours. Many colours are lost. It is an old format, made for when computers / internet connections were much slower / screens smaller / graphic hardware limited.
8 bpp ? That would be some sort of greyscale image. Are your images greyscale ?
If nothing like that please give some more details of your procedures.
As a comment, 1920x1200 is a monster size for an animated gif. I just made one from frames pulled out of a video and 12 layers gif = 11 MB file size. For comparison the same frames in the modern .webp format = 0.8 MB
