Wow Ray, that' fast!
You ask for predictions but less than one hour later, the outcome of 8/10 games is already revealed

(and now 10/10!!)
But an interesting comparison. I would have guessed a more balanced result, as I have Chess Genius Android in my private list with 2490 CElo; and TKP with 2529, so about "only" 40 points above.
But in addition, my Android is an old Galaxy Tab 2, featuring 2 ARM Cortex A9 cores@1.01Ghz.
I can confirm Chess Genius only uses one core (so the performance gap is not so much to your Tab A8, apart from twice the Mhz) and I do agree it does not scale that well with more speed. Your results confirm!
Thanks for the games
