Hi Ksquared. Thank you for your feed back.
I must say that it's been really hard to find a Kobo without this shadows. I already tried 4 Kobos and they all had shadows. The last one (in the image) is the worst.
I must have been very lucky with my first Kobo as it had a really clean and uniform frontlight.
Unfortunately I have to resign myself to the fact that I hardly will find another as the first.
Even though what you shared proves my firmware theory (about this shadow issue being solved in 3.15 firmware models) wrong, it still intrigues me the fact (because the opposite makes more sense) that a Kobo bought in February had installed the firmware 3.15 while all the currently available ones come with the 2.8.0.
Well... since I can't find one Kobo that does not have this issue, I don't have other way but get used to it.
