Updated and found that the Soft Proofing bug that gives erroneous RGB values is still there. Only LR 5.7.1 or older will give you the proper RGB values. This is crucial for anyone who wants to print their images. Example, a grey patch which reads in PS as 153/150/149 will read the same in LR 5.7.1 but will read as 82/79/79 in LR CC 2015.3.
