NOPE. They not only abandoned their once great BC program but there are MORE Xbox One exclusives that MS never bothered updating for 4k/60 than Sony. It's crazy to see that MS still enjoys the reputation as being "great for BC" when they so many exclusives are stuck at 720p-900p and 30 fps! Sunset Overdrive, Dead Rising 3 (great game btw), Ryse, Quantum Break, Forza Horizon 3, Gears Ultimate all never received patches!
Remember when DF did a special hyping up the Series X's BC capabilities and they had gotten to play Gears Ultimate at 4k and 60 fps? Yeah, how come we never got that as SX owners?
MS completely abandoned their BC once they got their sights set on GamePass which is akin to MS abandoning Series X owners since all those games that need patches are all on Gamepass.
They should've been keeping their promises with BC, patching games out of 720p hell, and bolstering GamePass in the process! They should've also kept the BC program going to improve all the games that they had to downgrade to One S settings/resolution when they added FPS boost. Games like Gears 4, Far Cry New Dawn, etc are only playable at 60 if you take a huge hit to IQ ...who wants that? The Series X is capable enough that with some more work they could've gotten these games running better at 60 fps.
And one more thing ...now that Microsoft owns Bethesda and Activision WHY aren't they patching all THOSE publishers great exclusives for 4k/60? All the Call of Duty games, Dishonored 2, Spyro Remake etc
That's just the thing though. The reason Sony has yet again beaten MS is because MS is always distracted and never focused on the things that gamers want them to be focused on- great games, great BC, pushing the Series X hardware etc! It has been a horrible gen for console gamers precisely because these companies started focusing on subscriptions and the PC market AT THE EXPENSE of many of the promises they made at the start of the generation.
