I just got off the phone with my reliable Swarovski contact on this issue. There was no change to the optics since the upgrade to SV. Then SV upgrade became the SV FP (field pro). When the NL's came out, swaro changed the focus mechanism on the EL's to a less expensive design, to be able to lower the price and still keep the optical quality of the EL. This resulted in a longer short focus, but all else stayed the same.
Therefore the difference looking down the barrels are not different from something made a month ago or a two years ago. The difference the OP sees is the change Swaro made to the focuser, not the optics. There is no less flat field or difference of color rendition from SV, SV FP and SV FP with changed focus mechanism. Of course there could be a small amount of unit variation I suppose in color, if your eye can pick that up, but id be extremely surprised.
