Testing build: furnaces +300% speed, input filtered inserters with iron ore/copper ore (activated in the same moment), output fast inserters.
After inserting 3 iron ore filtered inserters will be switched to copper. After copper - to iron and again from the beginning.
Signals from output inserters is compared each tick and if it is not equal lamps will be switched on.

Simple build: everything works as expected: During smelting lamps were switched off.

Advanced build: now I've added 100k stone in requester chest. During smelting lamps were switched on.

Why lamps are flickering?
In my opinion this happens because each bot-based delivery changes input chest contents and awakens all sleeping inserters, as a result they might start rotating 1 tick earlier. In other words game optimisation that was added (introducing "sleeping" state) affects game mechanic.

Expected behaviour: results should be the same in both experiments.

The sleeping inserter mechanics have existed since before 0.10. What you're describing is expected behavior and is unlikely to ever change.

This means I can connect flickering combinator to filter inserter (set filter mode) and their rotation time will be 1 tick less. This is nice.
