Hi Jack,
8-bit and L8 are not necessarily the same. Either way, 8-bit is not yet supported in TouchGFX. Actually, it is, but we cannot release it yet - So, the next version will be 4.12 which will be released as soon as we can align the version with CubeMX.
On your own you would not be able to make it work either because you need to rewrite the LCD class that understands how to write to 8-bit framebuffers, and LCD classes is closed source.
We will keep you updated!

I'm interested to know if TouchGFX now supports 8-bit L8 mode with CLUT on H7 MCUs?
