Differences are reported due to missing LCA related CRs. Since LCA is used for upgrading the nodes by using the image based upgrade procedure I think these CRs should not be a requirement as it doesn't apply to all environments:

Required CR by the reference "required/lca/LcaSubscription.yaml" is missing from cluster

Required CR by the reference "required/lca/LcaSubscriptionNS.yaml" is missing from cluster

Required CR by the reference "required/lca/LcaSubscriptionOperGroup.yaml" is missing from cluster
