I am more inclined to believe that PAF/PA for some reason, likely risk aversion, that did not employ their mid/long-range SAM systems to their maximum extend.
We did have visuals of successful interception, allegedly around PAF Rafiqui base (still trying to geo-locate this mosque, help appreciated). There are
, may or may not be the same interception.
And interestingly enough, Rafiqui is among the bases claimed to be damaged by IAF but no proof provided so far (not included in IAF presser and not among the Maxar images purchased by Indian media NDTV, correct me if I am wrong).
If this is true then the base(s) where PAF/PA did decide to employ advanced AD seems to be protected.
Well does this mean PAF/PA did not deploy advanced AD systems around those attacked and damaged ones? Not necessarily. Some of those bases do host strategically important assets (AEW&C, nuclear weapons etc.) that Pakistan has a strong incentive to protect.
But why there seems to be no proof interception (no video of interception or attempts, no debris of intercepted missiles, no debris of SAM falling to the ground if missed)?
One theory I have is that PAF may already know the scale of the attack to be small (from available footages roughly 2 missiles per base) would not amount to significant damage if not intercepted. So they may opt to keep SAM systems cold to avoid revealing positions and later attract SEAD/DEAD strikes. Because these nominal strikes could be "warning shots" or could be bait for AD systems.
The relative scarcity of SAM systems in general, and especially long-range SAM forced PAF/PA to make sacrifices in order to preserve interceptors and systems themselves.
