\setupcolors[pagecolormodel=auto]
might help
in acrobat, when transparency is used, a different route is followed (at
least in the past) when rendering
also, rendering colorspaces might be adapted to the output medium so
it's a combination of colorspace, monitor/paper, calibration,
knockout/overprint, transparency groups, assumptions etc
in the end, a print on a proper device is the reference
