How to check if view is added in a feature?
The features export views' code in files like this: my_module.views_default.inc. Every feature module with a file my_module.views_default.inc contains views.

Manually:

Searching against those modules by using the view's machine name as an input, will show whether that view machine name is tracked or not, to any of these modules.

Using drush:

Having all your features updated drush fu-all -y do some changes to a view (save) and drush fl. The feature that will appear with an overridden status contains that view, otherwise the view is not tracked yet. To see which features contains views code do drush fc --exported and select views_view, that will narrow down significantly the searching range.
