It's a subtle change, but one I definitely noticed. Check the official forum for an early comparison of the XB1 and PS4 versions in screen shots, and you'll see the difference in gamma that used to exist between them. The X1 version was the same as PC, but for some reason the PS4 version had a yellow-y look about it, and it looked a little flatter and less vibrant as a result. I'll try find it and post a link.
Edit: Here it is.

The thread died ages ago before the reason for the differences was discovered. I found in another thread someone from SMS stated the reason was the gamma was wrong on the ps4 version, and there were also other things wrong at the time (reflections were all messed up on ps4 too) that they were working on. They have since fixed the gamma, improved the shadows, and not only fixed the reflections, but massively increased the resolution of the reflections on the PS4 version. No doubt they've made other tweaks here and there too, and it's all added up to the crisper, clearer version we have now on PS4. Colours are more vibrant, as well as more natural and realistic. The image is also much sharper than it was in the 2.0 version from these images.
Sms really have made huge strides with this game. On PS4 it looks significantly better than it did at launch, has way less bugs, and the frame rate is silky smooth as well. Any doubts I had at launch that SMS could fix all the issues this game shipped with are long gone now. In 4 months they've turned it around significantly. It reminds me of the huge turnaround Evolution managed with Driveclub. Disaster at launch turned into an outstanding game within a year. I can only imagine how far Pcars will go in a year!
