device with even light and indented screen.

I found that my boox nova pro catch glare of light bulb on the ceiling and need to move around to be able to read. Backlight is very uneven. At some point top of screen would be yellow-ish and bottom half would be blue-ish. The light leak at bottom edge annoys me all the time. I heard that kobo forma has light band issue too.

Any advice on devices without those issue?:thanks:
