There are no e-readers that can match lets say printer paper or as you have shown a block of paper. Another thing to consider is there is no STANDARDISED variety of paper (direct experience in this sector as a scientist and artist). What I mean is that it paper surfaces and colour (even described as white) vary considerably. Unbleached recycled paper vs highly reflective white paper etc... But the bottomline is that typically e-readers can appear to either have a newspaper like feel to it when they don't have integrated lighting or the front light is turned off and it also depends on they type of screen lamination etc.
I have 4 e-ink devices: 1. Onyx Boox Max 2 Pro, 2. Onyx Boox Nova Pro, 3. Likebook Mars 7.8 inch, 4. Kindle Paperwhite (purchased in 2017).
I took a white square piece of paper (printer paper) and cut a hole about 7cm in diameter. When all the devices were fully powered off, I compared the screens. Indeed, there are some variations (but very subtle) which change in different light conditions (natural light, desk lamp, time of day, professional day light I use for my art work).
Comparing these screens (devices turned off), I found that the Nova is ever so slightly greyer (darker) than my all three devices: Kindle paperwhite (more white than grey), in second place is Likebook Mars, in third place is Max 2 Pro (this is grey with a creamy yellow shade, in the fourth place is Nova Pro (ever so slightly greyer with a bluish hint). But these variations are very subtle. Onyx Boox Max 2 Pro is the only e-reader from this list that does not have integrated front light, but personally this is my favourite.
I have a handheld usb vis-infrared spectrometer. I don't think it would work as the Nova has a glass lamination while the other screens will have plastic coatings, these will not make the comparison meaningful.
Typically most e-ink screens do have a greyish colour as you know, but perhaps the glass lamination (differences in refraction) with the front light make the Nova Pro ever so darker but this difference is marginal and really down to light conditions and is somewhat subjective.
