B1 oled seems to have a slightly changed BFI

Looks like it's capable of single strobing 60hz at around a 50% duty cycle, that's enough to take the edge of 60hz sample and hold blur and still maintain half the original screens brightness.

I find this blur reduction to be worthwhile and nice for retrogaming, also using high duty cycle bfi with reduced brightness can give flicker sensitive people some relief.
