For now, DI views are not shown in MM - it's something that was requested a while back. Refer:
As I see it, IS views are used to combine multiple objects, and ideally not used to filter data where possible.
IS rule scores are used to aggregate to Scorecards to shown how an overall area is tracking. You can then export a URL of the Scorecard out or use elsewhere.
At a table level, you may want to understand how good the data you are using in a report is. So you could find a report, look at lineage back to the source table(s) and see the score to give you confidence on whether you could make an informed decision on the data. This use case has some holes from an MM perspective, particularly with respect to DI views but also that there can be too many layers between table and report in a warehouse environment when rules are built on the source tables.
Hope that answers your question.
