I have tried changing the sRGB to just about everything my macbook can offer through lightroom, and the same thing is always happening. It hasnt done that before but after the update, it definitly changed.
I wonder if I'm having the same issue. images look fine and then exported to edit in photshop and color changes. for me, I lthink lightroom upgrade reset my preference menu/external editing/editing in photoshop color profile to ProPhoto RGB and need to work exclusively in sRGB
