Lightroom gives a tone curve rather like film in its default setting

Well, you can get this characteristic already. If you process a raw file in Lightroom 4 or 5, the default tone curve tails off the highlights just like film did. Approximately the top three stops of the recorded dynamic range (from the sensor) are compressed into one stop in the visible image.

I understand this was introduced by Adobe with their Process 2012 (introduced in that year, I presume). Earlier versions of Lightroom used a default tone curve with a sharper cutoff of the highlights.

So, if you process raw images through Lightroom 5, you automatically get this characteristic - much more reminiscent of the old days of film. Also, by compressing the top three stops into one, this means that the large dynamic range of modern cameras is used more effectively. Lightroom doesn't throw away any information from the highlights in the default setting, as far as I can see.
