BTW, I suspect that a low voltage there (0.8V) may cause instability, low level oscillations possibly. At least the sim suggests this, and it makes sense because the splitter transistors will both be very much turned off, harming the feedback loop.
Instead, if you set to 1V, at least one of the splitters will have a few uA of bias. More stable.
