In the (UK) developer job ads there is usually something along the lines of "a degree in computer science or relevant experience". Based on my experience I am guessing that this only matters for the purposes of getting through the recruiter / HR gatekeeper filter - once your actual tech chops are being considered no one cares, in fact not having a CS degree may well be to your advantage (CS does not teach you how to become a good software engineer, nor does it teach you the soft skills).

That said, without the CS education (formal or otherwise) some fields of work will be inaccessible but I think these are in the minority.
