I've flown on two aircraft (both 739s) with these the last two weeks and for the most part they look just like the regular sky interior so unless you are paying attention I think it's difficult to notice.

It wasn't until I was sitting there for a bit that I said to myself.. "Wow those bins look massive. Are these the new space bins?" Then I got up and noticed the label on the bins. A few minutes later as other pax got on the aircraft the FAs made announcements confirming they were their "new bins and to turn your bag on the side".
