@browser32,
It not as simple as that.
Nothing can be said about 'truth' at quantum and cosmological levels of analysis, , except to argue ,like the Pragmatists do, that 'truth' is about
agreement as to 'what works'. It is clear that QM 'works' in as much as it allows for prediction of behavior of some physical phenomena, and even suggests observations which otherwise would not have been made.
One essence of 'the reality debate' is captured in part by Nietzsche's point that 'we cannot separate description from reality. Some descriptions are simply more useful that others depending on context. We cannot get beyond 'description' which follows Kant's point about that all we experience are
phenomena and never
noumena (things in themselves). And since phenomena occur in a 'subjective realm', influenced by such context as culture, this ultimately delimits ontological enquiry.
