Oh so this is an actual thing? For a long time, whenever I'd watch anime on Hulu - like Gundam IBO, or OPM, or My Hero Academia - I always noticed the screen suddenly getting darker during an intense laser-lights action scene but figured maybe it was my connection or a resolution issue. But it's actually done on purpose?It might have been a half assed seizure prevention thing, but like why drop frames on Goku when they could just dim him like they did Jiren? Dimming the screen is a super common seizure prevention thing, dropping frames not so much.
