You may be right about Bohr personally, though I
am not so sure, certainly many philosophical presentations
of the Copenhagen view present it as treating measurement
as essential to consitituting reality.

As to incompatibility with realism that
depends on ones view of determinism and temporal
reversibility. If one assumes temporal symetry
this is not the case.
