Yes, IWB releasing smart munitions, their accuracy can be adversely affected by :
Severe cavity aeroacoustics,
Unsteady shear-layer turbulence, and
High-pressure oscillations.

Lighter smart weapons are particularly sensitive to these dynamic forces .

As they are leaving there is a danger of the contact too . So they are pushed out by automated or mechanical means, which further excarcebate the issue.

I always wondered why it's a big issue to throw weapons from internal bay, I think that sums it up..

Tolun is not a free-fall munition. Therefore, it engages the target on its own after releasing from the aircraft, and the turbulence generated during the release does not affect it."

Maybe internal calibration systems are effected more?

You should get your facts right mate.
Besides, even if it were turbojet powered, it wouldn't change anything. You would still have to deal with release dynamics.

You would still have to deal with :
Seeker Acquisition problems: IIR, IR, or RF seekers can experience a delayed "lock-on" or distorted acquisition during going through thiş turbulent air beneath the aircraft fuselage.
Aeroacoustic problems: These causes high vibrations inside the open bay that would vibrate the internal seeker electronics, gyros, and inertial measurement units causing targeting faults before or during release.
Flow Disturbances: An abrupt transition from a calm internal bay to a near stormy air flowing bay would cause severe oscillations, and roll that could displace the munition off its intended initial trajectory.

I think the point is, it has control surfaces to make meaningful course correction long after its release as it glides for extend period of time to reach extended range. Hence adverse release dynamics shouldn't effect terminal accuracy.
