I'd say that the cover is more-or-less mandatory for productivity because you lose dimmer colors to the background without it, even with the OLED brightness jacked up to max.
Then again, they're doing obvious PWM to achieve the lower-than-max brightness levels which creates flicker reminiscent of looking at an old CRT monitor running at 60Hz, which for me is a disincentive to run at anything less than max brightness.
