Kindle Oasis 3 still has the white on black inverted text option

Oh, it flashes, but from what I gather (never seen one in person ;p), it's supposed to do some subtle frontlight modulation to alleviate the "burn your retinas off" brightness issue during the white flash.

(And, yeah, that's technically software, but it's baked into the fl & eink kernel drivers on Zelda. And that's different on Rex, which is why I was curious about what happens with the PW4 in practice).

Do you have any evidence of those flashes that the light indeed gets turned off or dimmed? I vaguely remember saying something akin of Amazon should implement turning off the front light during full refresh to make the experience better. And then a short while after someone else confirms that it is actually happening.

I mean, not to brag, it is a good idea, but it was only a thing that happened in my head. When that other person (not sure who mentioned it first) states that Amazon actually does that, I thought, wow cool, Amazon had someone else to have that idea.

Edit: never mind. Tried it out and it does look really stupid and funky. It appears to dim while full refreshing. Dim, not turning off. When it is done, for the shortest split second the page looks good, and then the damn light turns brighter to ruin the background from a darker grey to a light grey. Most likely that was one of the reasons I don't bother with inverse.

Can't describe if it really modulates in a funky way, or else, but meet my PW4 virtually here (light intensity was set at 15):

@DuckieTigger: Yup, that's the behavior I was expecting given the kernel sources (i.e., ramp down during flash, then ramp back up).

@PoP: Hard to tell, cameras already have a hard-time dealing with brightness/contrast changes during flashes .
