No, not enough. The empirically sufficient level is 1500:1. For example, almost all cinemas with DLP projectors show movies with an on/off contrast (not even ANSI) of 2000:1.
IPS today has allegedly reached 2000: 1 only in new models from LG. The rest of the semi-matte IPS have a hard time reaching 1500:1 in rare models like the Legion 7 Slim with 4k panels, at least measurements show that they are close to these numbers.
For example, in complete darkness, watching movies or TV shows on a screen with 1000: 1 is uncomfortable - the black level is too obvious. 1500:1 is much better, and 2000:1 is even better. AMOLED screens rule here, but they have serious drawbacks when working in normal office mode with text under lighting.
As for 4k, you again have a typical illiterate judgment of an ordinary layman - 4k is an ideal ppi. And that's it. The reasons why 2.5k is bad I have already written many times - read my comments. 2.5k should be removed from the market altogether.
Only notebooks with 4k@144-165Hz should remain. And no others, similar to smartphones, where 300+ ppi has long been the minimum norm.
