The 'drop in brightness' is a non-issue unless you are viewing HDR (which you won't be with sports).

(Low) there should be almost no drop in brightness (25% auto-compensation), but only a 25% reduction in persistance (MPRT). It should look a bit 'better' than BFI off because persistance is reduced with no other visible impact.

(Medium), you are matching what the C8 BFI delivered but with only ~half the brightness loss of the C8 (25% brightness loss rather than 50% brightness loss). Unless you already have OLED Light above 65, OLED Light can be increased to compensate for this brighness loss, so you have 50% the persistance with 60Hz flicker that should be as visible as it was on the C8.

(High), you are getting 3.5ms MPRT with the same brightness loss as the C8 (50%). You can again compensate for the brighess loss by ~doubling OLED Light (if it was no higher than 50), but 60Hz flicker will be at least as bad if not worse as it was on the C8.
The best setting for sports should be to use 50% BFI @ 120Hz (this should be the real 'Game Changer' - 3.5ms MPRT with only 25% loss of brightness). To use 120Hz BFI you need to engage SmoothMotion to frame-interpolate the incoming signal from 1080i60 (60fps interlaced) or 720p60 (60fps progressive @ 720p resolution) to 2160p120 ([email protected]
But the result will be 3.5ms MPRT @ 25% loss of brightness (which can be compensated by increasing OLED Light as long as you were below 65 without BFI) and with pretty much no flicker (flicker @ 120Hz instead of 60Hz).
