You are not claiming "IFR time". You can be IFR on a brilliantly sunny day if you choose.
You are logging time spent in charge of the aircraft whilst flying solely by reference to instruments - "Instrument time". This implies that you were not on top of or between layers - rather, you were in the clag.
If you can still look out of the window and fly with any success, it isn't instrument time.
Instrument Time has no value in your logbook, other than that you need certain minimum amounts of it for certain licences under some regimes. It is therefore playing a role quantifying your genuine experience flying an aeroplane in soup.
If you bend the rules by claiming every IFR flight regardless of the inflight conditions, or by claiming flight in the clear, between layers, then the real loser is you.
