I have a Samsung Galaxy S9 and dark mode on its OLED display makes for a very nice reading experience. I could never read for very long on the LCD display on my old Moto G5 Plus. IMO, a black background on an OLED display is the next best thing to e-Ink. A larger display would be better to read on, but then my S9 isn't my primary reading device and I prefer a phone that can be used one handed.
Oh, and upgrading from Aldiko to Moon+ Reader Pro improved my e-reading experience as well.
