Guess what! Today I finally got a chance to unpack the sofa. The color is still different! Is it designed this way (3rd pic for new delivered sofa)

Update Feb 27th
A new sofa was shipped to me. It looks great.

Warning! The right session has different color than the rest. Dark grey vs Light grey! I waited almost a month and got this. UNACCEPTABLE. I am waiting for Wayfair’s response.
