I formatted an external 2TB (MBR) drive to exFAT and was able to choose 128KB cluster size

However when I formatted a 4TB (GPT) drive to exFAT, the smallest I was able to choose is 256KB.

Not that I'm worried about slack space (mainly huge files), but does anyone know why I am limited to 256KB? I couldn't find any information that clarifies this.
