Draw rates in classical chess between elite players? I'm looking for detailed statistics exhibiting draw rate for elite players. I did find this and this publications, however, they only contain aggregated data for 2600+ players, and arrive at a figure of about 55% for equal 2600+ players. 

This strikes me as completely inadequate estimate as far as elite players are concerend. I checked randomly some pairs of top players on chessgames.com, and the draw rate is usually more like 70% to 80% (well, for Carlsen-Ding Liren it's currently 100% with the sample of 9 games). This is consistent with the data that I got by checking some random elite tournaments - they have anywhere between 20% and 40% decisive games, most of them usually between players with larger rating difference. This is also consistent with betting odds - they indicate the probabilities of draw between 75% and 83% for the ongoing Altibox Norway chess tournament.

Is there a detailed statistics on how a draw rate varies with (a) rating
 difference and (b) average rating of the two players involved, similar to one linked above but with a detailed breakdown in the range of 2600-2800? Ideally with color breakdown, so that one can extract data such as "if a 2720 player plays white against an 2770 player, then the probability of draw is such and such"...
For over 2700 rated players,  statistically the draw rate is slightly under 50%.

For all over 2200 ,  the rate is just under 40%, statistically.
