I've tested around with the Seeed EN05 and 2-gray and 4-gray configurations on a 7.5" screen.
2-gray works flawlessly, 4-gray is washed out and definitely not working properly. I was able to isolate the EN05 being the problem by testing three EN05 (always the same result) against an EE04, each tested on two screens.
4-gray comparison Seeed EN05 vs Seeed EE04
EN05
note the washed out greys at the bottom, the QR code on the right-hand side of the screen and the logo in the top-right-hand corner
EE04
note the clear greys and no washed out logo and QR code
Let me know if there's more information I can provide or anything else I can test.
