Sure, here's a satellite image with annotation:Interesting claim. Do you have one of these side by side comprising ?
I was of the impression that the 052D merely ended up with a larger draft and thereby as a consequence a larger waterline beam. That’s why people tend to say that the 052D hull design is essentially maxed out.
The benefit of dual hangars is the ability to keep helos to perform ASW patrol for much longer or to rapidly prosecute a suspected contact in tandem. Anyone who has played a sub sim will know how deadly ASW helos can be as unlike a ship they give very little warning time for evasive maneuvers.
The fact that Type 054B, Type 054A and Type 052D all have a single hangar tells me that PLAN foresees a different naval platform to play the principal role in airborne ASW (Type 075?).

You can also simply measure the length on the screen on any side-by-side pic, e.g. this one:

On every single comparison, 052D is wider by about 1m compared to 052C. The most specific information I found specified 052D as having a beam of 18.2m, which is 1.2m more than the 17m usually stated for 052C.
There is no change in length between 052D batches 1 & 2 compared to 052C, but as a result of the increase in width and new radars, cooling system and VLS, displacement is increased by about 500 tons or so.
