Genomelink has paleolithic matching. I uploaded a 36.6k 23andme API file, and It says I am 0.17% matching with Salkhit DNA found 2009 available here https://www.ebi.ac.uk/ena/browser/view/PRJEB29760. Thats around 625 SNPs from a 34kya sample and I don't know the size of the Salkhit SNP file. That is amazing to know. I have gotten big percent match with Bacho Kiro samples and Ust Ishem, so this is in line with it but the age of the sample and amount of Denisovan part in it is a big news.

We estimate the proportion of Neanderthal ancestry in the Salkhit genome to be ~1.7% (table S17 and fig. S15), similar to other early Eurasians. As is the case for other Eurasian individuals, the Neanderthal ancestry in the Salkhit individual is equally related to the two Neanderthals from Vindija Cave in Croatia and Chagyrskaya Cave in Siberia who are ~50,000 and 80,000 years old, respectively, and less related to the ~120,000-year-old Siberian “Altaļ” Neanderthal from Denisova Cave (20, 26, 27) (fig. S16).
Using data from ~1.7 million SNPs where Neanderthal and/or Denisovan genomes differ from present-day African genomes, we detected 18 segments of Denisovan ancestry longer than 0.2 cM in the Salkhit genome (Fig. 3, table S18, and figs. S17 and S28) and 20 such segments in the Tianyuan genome (table S18 and figs. S19 and S28).

Salkhit overlap is found among East Asians, Hawaii and Telugu people in India (where K2b and F2 ydna is also found)
