PS4's sales curve is not indicative of being cannibalized, it would've dropped much faster from 2017 on if Switch was really a direct competitor.

You can't be sure. The PS4 sales curve may have been stronger without the switch. It may have reach 22M for example in 2017 and 20M in 2018, and 16-17M in 2019. There is no way to know.

There are very few things in the universe we can know with absolute certainty. We can make educated estimates though, and PS4's sales did not start to dramatically degrade in parallel with the Rise of the Switch, nor was the Switch's growth suppressed by the PS4's dominance at its time of release, so the most likely explanation is that the two didn't directly clash.
