Aim for photorealism

Looks like this solved the issue. Thank you !

How do you guys achieve blue sky color like this https://pixabay.com/sk/modrá-obloha-mraky-vonku-scénický-290314/ ? By connecting to cc node and increasing contrast and then compensating intensity ? Or is there any more physically correct way to do this ? Because by default sky looks a bit washed out

Your link doesn't work, but rich blue Sky happens as a combination of:

1) Correct angle, mostly frontal lighting.
2) Exposure blending
3) (optional, but greatly helps) Polarization filter
4) Post-production (selective color/contrast).

Have you seen recent making of by Santi Sanchez on Ronen Bekerman ? Go have look :- )

You want this, right ?

I am looking for something like your example but a bit less strong like in this link https://pixabay.com/sk/modr%C3%A1-obloha-mraky-vonku-sc%C3%A9nick%C3%BD-290314/ . I went over that making of and it´s great . As for exposure blending - does it mean only the sky would be the element here that would be replaced by lower exposure image?

[Juraj]

You have to consider part of that darkening is actually lens vignetting. Hence why this is good to do in post-production and not merely by under-exposing background override alone.

Thank you - you´ve once posted a pdf with some sun/sky examples and there were two ocean renders - one interior and one exterior - was the deep sky effect done purely in postproduction in that case ?

I honestly don't remember, I'll look it up.
