Disabling features, possibly at the hardware level with e-fuses is far more straightforward than trying to allow one sort framebuffer capture (screenshots) but not another (video recording).
>See the enterprise browser market (e.g. Talon, Island), which has granular policy and security controls for web content.
How secure are they though? It's one thing to make a chromium fork with "if is_porn_site(url): block()", it's whole different thing to implement a cryptographic system that can withstand physical attacks.

That depends on whether enterprise insiders have more or less economic incentives than media pirates. One of the enterprise browser vendors exited for ~600M USD to Palo Alto, so perhaps the security bar is only at the level of corporate firewall rather than gaming console.
