Unfortunately not, certainly not on mobile. I don't know if this is the case on iPhone, but on Android some apps make it really hard or impossible to screenshot them.
I think in recent Android versions they can even prevent the screen from getting mirrored to a connected PC / other casting device.
We are not allowed to take a screenshot on a device we own, for content we paid for. What a world.
Note: I mean Digital Restrictions Management[1] here, not Direct Rendering Manager[2].

That is also the reason why Linux doesn't (and likely never will) get served high resolution content by any significant paid service however.
I do faintly recall not being able to see video player content in screenshots taken on Ubuntu (but the player itself could take snapshots just fine) because of a divide like this some years ago.
I can vaguely understand the security concern, but it's my device, running my OS, why can't I make a simple screenshot?
I know sharing a screenshot of my bank statement is a bad idea, but forbidding it completely is a ridiculous extreme.
(On Android, you can only get into that swamp by opting in to "accessibility" features, which specifically need access to screen contents.)
Accessibility is only required if the app doesn't have system permissions, or if it's not carried out a privilege escalation. Though granted a privilege escalation might also be able to gain root to turn off setting a secure surface too (that's not enough to get past Widevine if that's been used but banks generally are not).
It's not about screenshots, the point is that screen recording is blocked because the OS can't see the encrypted video path. As it can't there's nothing to take a screenshot of.
(Indeed, you can take a screenshot. It just comes out with all the video data nulled, so it's a black square.)
EDIT: I stand corrected, the button combination does not work when the phone is unlocked and it always uses the rear camera. But I guess at least in principle one could build this.
I briefly used Android and the fact that applications can prevent screenshots is a horrible decision, closer to DRM than to a user-centric design.
Maybe not, but it’s all the same if they can make the screenshot useless. Using Netflix as an example: when you take a screenshot video controls will be visible, but the content behind them won’t be.
