If the brightness is just enough then it looks very like eink. Except eink is reflecting so the white balance always is identical to ambient. Unfortunately the white balance software is flawed on the Nxtpaper 11, so neutral is best. That will look warm in some ambient conditions and by tungsten ambient or very warm colour temperature LED it will look cool.
Finding Dark mode better suggest the brightness is too high. Also black text on white paper (or dirty colour of PDF scan) is sharper on a colour display than white text on black.
Also "Dark" mode is only going to work properly with pure text. No use for scanned PDFs or Video etc.

Hey, I've finally decided to give Nxtpaper 11 a try(and still have few days left to return if I won't like it). So far Nxtpaper screen is pretty good and device itself is interesting albeit as you said before, there are obvious flaws like dimensions and aspect ratio.
Anyway, reading your post above I'd like to ask about optimal settings for reading, my current ones are:
- NXTVision enchacements(Image, Video Game) on. No idea what they do, should those be off?
- Reading mode off. This one seems to be just basic BW monochromancy mode available on almost any recent android device in developer options.
- Eye comfort mode off. This one is probably just software color tint commonly available on most devices.
- Sunlight display mode off. (Do you know what does it do? It says it "Increases readability under sunlight" but after tests I can't tell the difference.)
- Color mode & temperature set to advanced and default sRGB(dot directly in center of color wheel).
- Gamma 2.0(Sharpness).
I found that NXTPaper is not good in direct sunlight but given it's mobile device, it's possible to just move around to find darker spot and with maxed brightness visibility gets bit better(just using own body to cover the sun is making huge difference - black screen vs poor but visible text).
Also found that lowest brightness(2%) is probably bit too bright for completely dark environment but software light dimmers are good workaround.
I still don't know does TCL NXTPaper 11(NXTPAPER 2.0 screen) use PWM or not. According to data from TCL website DC Dimming was introduced with NXTPAPER 3.0 but I've done some testing with camera and couldn't find any PWM, even at lowest brightness. But then I've found some online people claiming they tested NXTPAPER 2.0 with professional tools and it does have PWM which is especially visible at 50% brightness or lower. Confused here...
Also wondering does NXTPaper 11 use Temporal Dithering and if so, is there any way of disabling it. Perhaps there's some relation to NXTVision enchancements?
EDIT:
Did anyone notice that this device has probably uneven light distribution? It's noticeably dimmer on the side of back camera. Easy to spot when using white background in landscape mode. Is it normal or my device is faulty?
