I want to get a macbook of some sort and intend to do photography with it. Display quality is therefore important. Other threads suggested apple are putting one of two display panels in the rMBP13 2015. You can check by using the color profile info tool to see of the panel code ends in 029 (LG good?) or 2A (Samsung bad?). I popped into both London apple stores to investigate. Regent Street had one with an LG display and it looked good. The Covent Garden had one with Samsung and looked visibly warmer and possibly fuzzier but this was not a scientific test in the busy store just before closing time. Staff at both stores had no idea abiut this or how I could get the right one. So...how do I get the right one in the UK?
