Yes, unless I'm greatly misunderstanding the tables, what the study actually measured is that: * Spatial intelligence is positively correlated with socio-economic status. * Screen (TV + Digital) time is negatively correlated with socio-economic status. Concluding from this that spatial intelligence is negatively correlated with screen time is dubious. Similar reasoning is used to promote all kinds of class-correlated fashions, e.g. breast feeding.
